E-Commerce Platform

Project Overview

The E-Commerce Platform represents a comprehensive, production-ready solution for handling complex retail operations. Built from the ground up with scalability and reliability in mind, this platform processes millions of transactions annually while maintaining exceptional performance.

Key Features

Real-time Inventory Management

The system tracks product inventory across multiple warehouses with sub-second latency using Redis caching and optimistic locking strategies.

• Automatic stock level synchronization
• Low stock alerts
• Multi-warehouse support
• Inventory forecasting

Payment Integration

Secure payment processing with Stripe ensures PCI compliance and supports multiple payment methods.

async function processPayment(orderId: string, amount: number) {
  const payment = await stripe.paymentIntents.create({
    amount,
    currency: 'usd',
    metadata: { orderId },
  });
  return payment;
}

Admin Dashboard

A powerful administrative interface built with React and TypeScript provides insights into sales, customer behavior, and operational metrics.

• Real-time analytics
• Order management
• Customer insights
• Reporting and exports

• Uptime: 99.95%

Challenges & Solutions

Handling Peak Traffic

During peak shopping seasons, we implemented horizontal scaling with load balancing and database read replicas to maintain performance.

Inventory Accuracy

Real-time inventory proved challenging with concurrent orders. We solved this using database-level locking and a queue-based processing system for order fulfillment.

Payment Reliability

Integration with multiple payment providers and fallback mechanisms ensured payment processing reliability during outages.

Results & Impact

This platform has become the backbone of the company's e-commerce operations, enabling:

• 10x increase in transaction throughput
• 40% reduction in checkout time
• 99.95% uptime over the past 2 years
• Support for $2M+ in monthly transactions
