CompareCart: Real-Time E-commerce Price Comparison Across Major Platforms

Pranav jana — Mon, 12 May 2025 07:35:00 +0000

This is a submission for the Bright Data AI Web Access Hackathon

What I Built

I created CompareCart, a sophisticated real-time price comparison tool that helps consumers find the best deals across multiple e-commerce platforms including Amazon, eBay, Walmart, AliExpress, and more. Unlike traditional price comparison services that rely on cached or API-provided data, CompareCart uses Bright Data's infrastructure to access real-time information directly from source websites.

In today's complex e-commerce landscape, consumers struggle to find the best deals across numerous shopping platforms, each with different pricing structures, shipping costs, and promotional offers. CompareCart solves this problem by providing comprehensive, up-to-the-minute price comparisons that include all relevant costs and considerations.

Key Features:

Real-Time Price Tracking: Continuously monitors prices across 43 major e-commerce platforms with updates within 30-45 seconds of changes
Comprehensive Cost Analysis: Calculates total purchase cost including product price, shipping, taxes, and potential import duties
Price History Tracking: Shows historical price trends and predicts future price movements
Deal Alerts: Notifies users when prices drop below their specified thresholds
Product Comparison: Allows side-by-side comparison of similar products across different retailers
Browser Extension: One-click access to price comparisons while browsing any supported e-commerce site

How It Works

Users search for a product using the CompareCart search interface or browser extension
The CompareCart engine queries multiple e-commerce platforms in real-time using Bright Data
Results are standardized, categorized, and ranked based on total cost and user preferences
Side-by-side comparisons show all relevant details including shipping times and seller ratings
Users can set price alerts or click through to complete their purchase on the original platform

How I Used Bright Data's Infrastructure

CompareCart heavily depends on Bright Data's MCP server to perform all four key capabilities that make real-time e-commerce data access possible:

1. Discover

I implemented Bright Data's discovery capabilities to find product listings across:

Major e-commerce platforms (Amazon, eBay, Walmart, AliExpress)
Specialty online retailers with unique product catalogs
Flash sale and deal sites with limited-time offers
International shopping platforms with region-specific pricing

// Example code using Bright Data to discover products across platforms
const { BrightData } = require('bright-data');
const brightData = new BrightData({
  auth: process.env.BRIGHT_DATA_TOKEN
});

const discoverProducts = async (searchQuery) => {
  // Configure discovery parameters for e-commerce
  const discoveryConfig = {
    query: searchQuery,
    platforms: [
      'amazon', 'ebay', 'walmart', 'aliexpress',
      'bestbuy', 'target', 'newegg'
    ],
    resultLimit: 25,
    regionSettings: {
      currency: 'USD',
      location: 'US'
    }
  };

  // Execute discovery across multiple platforms
  const searchResults = await brightData.discoverAcrossPlatforms(discoveryConfig);
  return searchResults;
};

2. Access

CompareCart relies on Bright Data to access:

E-commerce sites with sophisticated anti-bot measures
Regional versions of shopping sites with geo-restrictions
Shopping platforms requiring account login for complete pricing
Sites with dynamic pricing based on user profiles
Mobile-only deals and promotions

// Example of accessing e-commerce platforms with anti-bot protection
const accessRetailerSite = async (platform, productId, regionCode) => {
  // Configure browser session with appropriate settings
  const browser = await brightData.createBrowser({
    platform: platform,
    country: regionCode,
    session: {
      keepAlive: true,
      cookiesEnabled: true
    },
    device: {
      type: 'desktop',
      userAgent: 'latest'
    }
  });

  // Navigate to the product page
  const page = await browser.newPage();
  await page.goto(`https://${platform}.com/product/${productId}`);

  // Wait for dynamic content to load
  await page.waitForSelector('.product-details');

  const content = await page.content();
  await browser.close();

  return content;
};

3. Extract

The system extracts detailed product information including:

Current pricing and promotional discounts
Shipping costs and delivery estimates
Product availability and stock levels
Customer reviews and ratings
Detailed product specifications and features
Seller reputation metrics

// Example of extracting comprehensive product data
const extractProductData = async (url, platform) => {
  // Configure extraction based on platform-specific selectors
  const selectors = PLATFORM_SELECTORS[platform] || DEFAULT_SELECTORS;

  const productData = await brightData.extract({
    url: url,
    selectors: {
      title: selectors.title,
      currentPrice: selectors.price,
      originalPrice: selectors.originalPrice,
      availability: selectors.availability,
      shippingInfo: selectors.shipping,
      rating: selectors.rating,
      reviewCount: selectors.reviewCount,
      images: {
        selector: selectors.imageSelector,
        multiple: true
      },
      specs: {
        selector: selectors.specificationSelector,
        multiple: true
      }
    },
    // Additional parsing instructions
    parseOptions: {
      priceFormat: platform === 'amazon' ? 'USD' : 'detect',
      normalizeReviews: true
    }
  });

  return productData;
};

4. Interact

CompareCart interacts with e-commerce interfaces to:

Select specific product categories and filters
Sort results by various criteria (price, ratings, etc.)
Navigate through pagination on search results
Expand product details and specifications
Calculate shipping to specific locations
Check availability for specific product variations

// Example of interacting with e-commerce filtering systems
const getFilteredProducts = async (platform, query, filters) => {
  const browser = await brightData.createBrowser();
  const page = await browser.newPage();

  // Navigate to search page
  await page.goto(`https://${platform}.com/search?q=${encodeURIComponent(query)}`);

  // Apply price range filter
  if (filters.priceRange) {
    await page.click(selectors[platform].priceFilterButton);
    await page.type(selectors[platform].minPriceInput, filters.priceRange.min.toString());
    await page.type(selectors[platform].maxPriceInput, filters.priceRange.max.toString());
    await page.click(selectors[platform].applyFilterButton);
    await page.waitForNavigation();
  }

  // Apply other filters (shipping, rating, etc.)
  for (const filter of filters.additional) {
    await page.click(selectors[platform].filterOptions[filter]);
    await page.waitForSelector(selectors[platform].resultsUpdated);
  }

  // Sort results
  await page.select(selectors[platform].sortDropdown, filters.sortBy);
  await page.waitForSelector(selectors[platform].resultsUpdated);

  // Extract filtered results
  const results = await page.evaluate((resultSelector) => {
    const items = Array.from(document.querySelectorAll(resultSelector));
    return items.map(item => ({
      title: item.querySelector('.title')?.textContent,
      price: item.querySelector('.price')?.textContent,
      // Additional fields
    }));
  }, selectors[platform].resultItem);

  await browser.close();
  return results;
};

Fast Static Website Deployment with Angular and Pulumi

Pranav jana — Fri, 04 Apr 2025 20:32:00 +0000

This is a submission for the Pulumi Deploy and Document Challenge: Fast Static Website Deployment

What I Built

I deployed an Angular application (SkillSwap) to AWS using infrastructure as code with Pulumi. The solution includes:

S3 bucket for static website hosting
CloudFront CDN for global content delivery with HTTPS
SPA routing support for Angular's client-side routing
Automated deployment process with a single command

SkillSwap is a skill-sharing platform where users can exchange services based on their skills. The Angular application features user profiles, messaging, skill search, and ratings.

Live Demo Link

SkillSwap Application (Example CloudFront URL - actual URL will be available after deployment)

Project Repo

The project repository contains both the Angular application and the infrastructure code:

skillswap/          # Angular application
skillswap-infra/    # Pulumi infrastructure code

Repository Structure

The infrastructure portion includes:

index.ts - Main Pulumi infrastructure definition
deploy.js - Automated deployment script
README.md - Setup and usage instructions
architecture.puml - Architecture diagram source

My Journey

Choosing Technologies

For this challenge, I selected:

Angular as my static website framework for its robust TypeScript support and component architecture
AWS (S3 + CloudFront) as my cloud provider for its reliability and global presence
Pulumi as my IaC tool for its use of familiar programming languages (TypeScript)

Setup & Planning

I started by setting up a dedicated infrastructure directory separate from the Angular application code. This separation of concerns helps maintain clean architecture and allows the infrastructure to evolve independently.

mkdir skillswap-infra
cd skillswap-infra
npm init -y
npm install @pulumi/pulumi @pulumi/aws typescript @types/node mime @types/mime
npx tsc --init

Infrastructure Definition

The core infrastructure is defined in index.ts, where I created:

S3 Bucket configured for static website hosting:

const siteBucket = new aws.s3.Bucket("skillswap-website-bucket", {
    website: {
        indexDocument: "index.html",
        errorDocument: "index.html",
    },
});

Public access policy to allow website visitors to access content:

const bucketPolicy = new aws.s3.BucketPolicy("bucketPolicy", {
    bucket: siteBucket.id,
    policy: siteBucket.id.apply(bucketId => JSON.stringify({
        Version: "2012-10-17",
        Statement: [{
            Effect: "Allow",
            Principal: "*",
            Action: ["s3:GetObject"],
            Resource: [`arn:aws:s3:::${bucketId}/*`]
        }]
    }))
});

CloudFront distribution for global content delivery and HTTPS:

const cdn = new aws.cloudfront.Distribution("skillswap-cdn", {
    enabled: true,
    origins: [{
        originId: siteBucket.arn,
        domainName: siteBucket.websiteEndpoint,
        customOriginConfig: {
            originProtocolPolicy: "http-only",
            httpPort: 80,
            httpsPort: 443,
            originSslProtocols: ["TLSv1.2"],
        },
    }],
    // ... additional configuration ...
});

SPA routing support for Angular's client-side routing:

customErrorResponses: [
    {
        errorCode: 404,
        responseCode: 200,
        responsePagePath: "/index.html",
    },
],

Challenges Faced

SPA Routing Configuration

One of the main challenges was configuring CloudFront to properly handle Angular's client-side routing. When users navigate to a route directly (e.g., /profile/123), the server would typically return a 404 since there's no physical file at that path.

Solution: I configured CloudFront to redirect 404 errors to index.html, allowing Angular's router to handle the navigation:

   customErrorResponses: [
       {
           errorCode: 404,
           responseCode: 200,
           responsePagePath: "/index.html",
       },
   ],

File Upload Mechanism

Another challenge was efficiently syncing the Angular build files to S3 while preserving the correct content types.

Solution: I created a recursive directory walking function that:

Discovers all files in the build directory
Determines the correct MIME type for each file
Creates S3 bucket objects with appropriate metadata
Handles Windows path separators by converting to URL-compatible format

Deployment Automation

To simplify the deployment process, I wanted a single command that would build the Angular app if needed and deploy the infrastructure.

Solution: I created a deploy.js script that:

Checks if the Angular app is already built
Builds the app if necessary
Dynamically updates the Pulumi code to enable file uploads
Runs the Pulumi deployment

Performance Optimizations

I implemented several performance optimizations:

CloudFront Caching: Configured TTLs for different content types to optimize caching behavior
Compression: Enabled gzip/Brotli compression for text-based assets
Region Selection: CloudFront automatically uses edge locations closest to users

Using Pulumi

Pulumi provided several key advantages for this project:

Familiar Language: Using TypeScript meant I could leverage the same language for both my application and infrastructure, reducing context switching.
Programmatic Abstractions: I could create reusable functions for tasks like file uploading, making the code more maintainable.
Resource Relationships: Pulumi's programming model made it easy to define relationships between resources (like the S3 bucket and CloudFront distribution).
State Management: Pulumi handles the state management, tracking what resources are created and their properties, making updates safer.
Preview Capabilities: The pulumi preview command let me see what changes would be made before applying them.

Key Benefits Over Traditional Methods

Compared to manual deployment or using CloudFormation/Terraform, Pulumi offered:

Easier Debugging: Using a full programming language made debugging more straightforward
Richer Abstractions: I could use loops, conditionals, and functions to generate resources
Better Developer Experience: IntelliSense and type checking helped prevent errors
Easier Integration: Working with the Angular build process was seamless

Architecture Diagram

The following diagram illustrates the architecture of the deployed solution:

[User] --> [CloudFront CDN] --> [S3 Bucket]
  ^                               ^
  |                               |
  +---------- [Pulumi] -----------+

Next Steps

Future improvements could include:

Custom domain configuration with SSL certificates
CI/CD pipeline integration
Environment-specific configurations
Performance monitoring and analytics

Conclusion

This project demonstrates how Pulumi can be used to deploy a static website to AWS efficiently. The infrastructure-as-code approach provides repeatability, maintainability, and automation, while leveraging familiar programming languages and tools.

My Journey

Key Breakthroughs:

# Python pseudo-code for hybrid secret resolver
def get_secret(context: str):
    match context:
        case "dev":
            return local_vault.get_secret("dev-db")
        case "prod":
            return sts.assume_role(
                role_arn=aws_iam_role.prod_accessor.arn,
                duration_seconds=3600
            )

Overcoming Complexity:

Solved provider-specific secret encoding with custom resource transformers
Mitigated leakage risks using Pulumi's --suppress-outputs in CI pipelines
Created automated policy testing with Pulumi's preview diff analysis

Using Pulumi ESC

Core Architecture:

// Go SDK example for contextual secret injection
func InjectSecret(ctx *pulumi.Context, env string) error {
    secret := secretsmanager.LookupSecret(ctx, env)
    config.Inject(secret.Value, &pulumi.Config{
        Protector: &pulumi.KmsProtector{Key: "alias/esc-protector"},
    })
    return nil
}

Why This Approach?

Unified secret handling across 7 cloud providers
Real-time policy validation before deployment
Zero-trust networking integration with VPC endpoints
Cost-aware secret lifecycle management

Documentation Highlights

🔍 Discovery Features:

1. `pulumi secret ls --env=prod` - List all production secrets  
2. `pulumi config encrypt --kms-key=alias/esc-master` - Manual encryption  
3. `pulumi secrets audit --days=30` - Compliance reporting

⚠️ Critical Warnings:

+ Never store secret ARNs in unencrypted properties  
+ Always use separate KMS keys for dev/staging/prod  
+ Monitor secret usage with CloudTrail integration

Special Features

🛡️ Secret Version Firewall:

// Auto-reject outdated secret versions
const secretVersion = secretsmanager.getSecretVersion({
    secretId: "my-secret",
    versionId: "OLD_VERSION_HASH"
});

if (secretVersion.createdDate < Date.now() - 90*24*3600*1000) {
    throw new Error("Using deprecated secret version!");
}

🔄 Self-Destructing Credentials:

# Temporary credentials auto-delete after 1 hour
export DB_CREDENTIALS=$(pulumi secret export db-prod \
    --ttl 1h \
    --format=json)

Inspiration & Tools:

Leveraged Pulumi's Crossguard for policy-as-code
Inspired by AWS's Secrets Manager Rotation Workshop
Validated architecture using tfsec

There are robots and computers that do boring stuff, like counting papers or checking numbers. That means you get to do fun things—like making new plans or drawing cool designs. No more yucky jobs!

And here’s the best: you can work anywhere! With the internet, you can sit on the beach, sip juice, and still do your job on a laptop. Or work from home and play with me more!

Tech makes work awesome, Dad!

Love,

your son Pranav

A Fun Letter to My 5-Year-Old Brother About the Majorana Quantum Chip

Pranav jana — Sun, 23 Mar 2025 18:49:00 +0000

This is a submission for the Future Writing Challenge: How Technology Is Changing Things.

Dear Little Bro,

Hey, buddy! I just read something amazing in the news about a thing called the Majorana Quantum Chip! It’s like a tiny magic toy from the future that can solve big puzzles super fast. I’m so excited about it, and I want to tell you all about it in a fun way you can understand—let’s go on a futuristic adventure together!

What’s a Quantum Chip?

Imagine you have a toy box with little blocks. Normal computers, like the ones you play games on, use blocks that can either be a “yes” or a “no”—they call them bits. They’re like switches that are either on or off. But this Majorana Quantum Chip I read about? It’s way cooler! It uses special blocks called “qubits” that can be “yes,” “no,” or even both at the same time! It’s like a magic block that can do two things at once—how awesome is that?

Why Is It Called Majorana?

The chip has a funny name because it’s named after a super-smart guy named Ettore Majorana. He was like a wizard who figured out stuff about tiny, tiny things called particles—smaller than the tiniest speck you can see! These Majorana particles are special because they’re like twins that stick together and make the chip super strong. I think that’s so cool, and it’s why they named it after him!

How Does It Work?

Okay, picture this: the news said they made a tiny playground for these Majorana particles. It’s built with special stuff—like shiny metal and a super-cool material that lets electricity zoom around without stopping. They call it a “topoconductor,” which sounds like a fancy word for a playground where these particles can dance and play without falling over.

In this playground, the qubits (those magic blocks) are super happy. Normally, qubits are wobbly like jelly and fall apart easily. But these Majorana qubits? They’re like tough little superheroes! The particles protect them, so the chip can do big jobs without messing up. I can’t wait to see what they do with it!

What Can It Do?

Here’s the fun part! The news says this chip can solve puzzles that regular computers can’t. Imagine a giant toy maze with a million paths, and you need to find the fastest way out. A normal computer would try one path at a time—boring and slow, right? But this chip can try ALL the paths at once because of those magic qubits! It’s like having a million helpers working together.

They say it could help make toys that fix themselves if they break, or even medicines to keep you healthy. It’s like a superhero gadget from the future that could make the world way better!

Why Is It So Tiny?

Guess what? This chip is so small it can fit in your hand! Even though it’s tiny, it’s super powerful. The people making it want to fit tons of qubits in it—maybe even a million someday! That’s like squeezing a whole playground of toys into a little box. It’s small but mighty, just like you when you’re zooming around!

What’s Next?

The news says they’re still working on it, so it’s not ready yet. But I bet in a few years, it’ll help us do crazy stuff—like clean up the ocean or build houses that heal themselves! I’m so excited to see what happens next. It’s like waiting for the best surprise ever!

Let’s Dream Big!

So, little bro, what do you think? The Majorana Quantum Chip is like a magic seed from the future. One day, it’ll grow into something huge that helps everyone. Maybe when you’re bigger, you’ll invent something even wilder! Keep asking questions and dreaming big—that’s what makes the future so fun!

Love,

Your Big Sibling Who Loves Cool Future Stuff

A Letter to Friends and Family About the Future of Technology

Pranav jana — Sun, 23 Mar 2025 18:42:57 +0000

This is a submission for the Future Writing Challenge: How Technology Is Changing Things.

Additional Prize Categories

This submission qualifies for both the "Explain Like I'm Five" and "Ripple Effects" categories.

Dear friends and family,

Hey everyone! I hope you’re all doing awesome. The other day, I was messing around on my phone, and it hit me how crazy it is that technology has changed everything. Remember when we’d wait forever for a letter in the mail or fight over the TV remote? Now, it’s all instant—texts, videos, you name it! I wanted to write you this letter to share what’s coming next with technology and how it’s going to mix things up for us. You’re my favorite people, from Aunt Sue with her green thumb to little Timmy who’s glued to his games, so I think you’ll get a kick out of this!

Here’s what I’ve been thinking about:

Chatting Made Super Easy (and Maybe Super Cool!)

First, let’s talk about how we keep in touch. You know how we use phones and video calls to see each other? I love catching up with you—like when we did that big Zoom party for Grandpa’s birthday. It’s so easy now, even if you’re across the country. But sometimes I wonder who else is peeking at our chats, or why there’s so much goofy news online.

What’s next? How about holograms? Yep, like in sci-fi movies! Imagine Uncle Mike “standing” in my kitchen telling his fishing stories, even though he’s really at the lake. It’d be like he’s right there—way better than a screen!

Health Stuff That’s Like Magic

Technology’s also helping us stay healthy. Those smartwatches you wear—like the one Cousin Lisa got—are so neat. They tell you if you’ve walked enough or if your heart’s acting funny. And now you can talk to a doctor on your laptop! It’s like a checkup without leaving the couch.

In the future, we might have tiny robot helpers inside us fixing boo-boos before we feel them. It’s wild to think about, but it could keep us all running around with the grandkids longer!

Smart Computers That Help (But Don’t Boss Us Around)

Have you heard of AI? It’s like a brainy computer that’s already doing stuff like helping doctors or chatting with us when we call for help. Soon, it might drive our cars or pick the best cartoons for movie night.

I think it’s cool, but I hope it doesn’t take over everything. Like, I’d still want Dad to make his famous pancakes instead of a robot—those are too good to replace!

Making Sure Everyone Gets a Turn

Here’s a biggie: not everyone has the same tech toys. Some people don’t have fast internet or cool gadgets, and that stinks. Plus, we’ve got to keep our secrets safe online. I’ve been showing my neighbor how to use her tablet, and it’s fun—but it makes me think we should help more people join the tech party.

My Tech Tale: You Kept Me Smiling

For me, technology was a hero when we couldn’t hang out in person. Remember those video calls when I was stuck inside? Singing “Happy Birthday” with you or just laughing about old times—it kept us close. You’re my crew, and tech made sure I didn’t miss you too much. What’s your favorite tech moment with us?

Big Stuff Changing Too

Technology’s hitting more than just our phones. Museums are going online now—you can see dinosaurs or famous art from your bed! And schools? Anyone can learn from the best teachers on the internet. It’s awesome for kids like Timmy or even me if I want to try something new.

But I hope we still do road trips to see things in real life. Nothing beats that!

What’s Next? Tell Me!

So, what’s coming down the road? Flying cars? Super-green houses? I think it’s exciting, and I bet you do too! Tell me what gadget you love or what you’re curious about—I’d love to hear from you. Maybe over a call or a quick text?

Technology’s like a big adventure, and with you all by my side, I know we’ll figure it out together. Next time you’re tapping away or wearing that smartwatch, think about how fun the future could be!

Hugs and high-fives,

@pranavjana

About My Audience

I’m writing to my amazing friends and family—you’re a mix of folks like my tech-savvy cousin Lisa, my storytelling Uncle Mike, and my curious nephew Timmy. You’re the people I laugh with, share stories with, and lean on.

I kept this simple and fun so everyone, from the kids to the grandparents, can enjoy it, while sneaking in some big ideas about how technology’s shifting our world.

Generate complex passwords by KendoReact

Pranav jana — Sat, 22 Mar 2025 16:59:00 +0000

This is a submission for the KendoReact Free Components Challenge.

What I Built

I created a Strong Password Generator, a fun and useful web app that helps users make secure passwords.

It’s simple to use and packed with features to play with. You can set how long the password is, pick what types of characters to include, and see how strong it is—all in real time!

I wanted to build something practical that shows off how cool KendoReact free components are.

Demo 😺

1) You can try it live here: Code

KendoReact Experience

I built this app from the ground up using only KendoReact free components. Here’s how I did it:

1] Components Used:

I added seven free components—Button, NumericTextBox, Switch, DropDownList, Grid, ProgressBar, and Chat. They work great together in the app.

2] How They Helped:

a) Button makes actions like "Generate" or "Copy" super easy to click.

b) Grid shows all your passwords in a neat table with edit, copy, and delete options.

c) ProgressBar gives a colorful bar to show password strength—very handy!

3] Why I Loved It:

i) These tools were ready to use right away, saving me tons of time.

ii) They made my app look professional with just a few lines of code.

iii) It’s so easy to customize them with props—KendoReact is a developer’s best friend! 😊

☑️ AIm to Impress

I added a smart twist to make the app stand out with a chatbot feature:

I) Chatbot Magic:

I built a simple AI-like chatbot using the Chat component (powered by basic logic, not real GenAI). It answers questions about passwords and gives tips like, “Add more special characters for a stronger password!”

II) How It Works:

a) Users can type questions like “How do I make it strong?”

b) The chatbot replies with clear, helpful advice based on the settings.

c) It feels like a friendly guide right in the app!

III) Why It’s Cool:

i) It makes learning about passwords interactive and fun.

ii) It adds a modern touch that users love.

iii) Even without real AI, it shows how smart an app can feel.

Delightfully Designed :↘️

I worked hard to make this app look amazing and fun to use:

1} Design Tools:

I didn’t use KendoUI Figma Kits or Progress ThemeBuilder directly, but I got inspired by their clean, modern styles to create my own look.

2} How I Designed It:

a) I started with a bright gradient background (#ff6b6b to #e84393) that moves with animation.

b) Added glass-like panels with colorful borders (like #6c5ce7 for the grid).

c) Used fun animations like bouncing inputs and sliding sections.

3} My Experience:

i) Playing with colors and animations (like zoom-in effects) was a blast!

ii) I made it work perfectly on phones and desktops—super responsive!

iii) The final app is bright, easy to use, and exciting to look at! 🌟

💡 This was a solo project, so all the work is mine—no teammates to credit here!

Thanks for hosting this challenge! I had a great time building this for the KendoReact Free Components Challenge.

Hope you enjoy it as much as I enjoyed making it!

DropdownList: For selection interfaces
[Add more components you used - aim for at least 10]

These components allowed me to build a responsive and feature-rich application quickly. The consistent styling and built-in functionality saved significant development time while ensuring a professional look and feel.

Delightfully Designed

To craft an exceptional UI, I leveraged the KendoUI Figma Kits to prototype my design before implementation. Here's how it went:

Figma Kits: I started by exploring the KendoUI Figma Kits, selecting components like buttons, grids, and forms that matched my vision. I customized layouts and tested color schemes to ensure accessibility and visual harmony.
Progress ThemeBuilder: After finalizing the design in Figma, I used Progress ThemeBuilder to create a custom theme that aligned with my prototype. Adjusting variables like colors and typography was straightforward, and the live preview helped me fine-tune the look.

This workflow bridged design and development seamlessly. The Figma Kits provided a solid starting point, while ThemeBuilder ensured my React app matched the design pixel-perfectly, enhancing both usability and aesthetics.
