Developed a custom e-commerce platform for ShopCorp, a mid-sized retail company looking to expand their online presence. The platform features a modern, user-friendly interface with robust backend functionality to handle high traffic volumes and complex inventory management.

Challenge

The client needed a solution that could integrate with their existing ERP system while providing a seamless shopping experience across devices. Key challenges included implementing real-time inventory updates, secure payment processing, and a personalized recommendation engine.

Solution

Built a React.js frontend with a Node.js/Express backend and MongoDB database. Implemented microservices architecture for scalability. Key features include:

• JWT-based authentication with role-based access control
• Product search with filters and sorting
• Shopping cart with persistent storage
• Stripe integration for payments
• Admin dashboard for inventory management
• Product recommendation engine using collaborative filtering

Results

The platform launched successfully with:

• 40% increase in conversion rate compared to previous solution
• 99.9% uptime during peak holiday season
• Average page load time under 1.5 seconds
• Seamless integration with client's ERP system

Lessons Learned

This project reinforced the importance of thorough load testing before launch. We initially underestimated the database requirements which caused performance issues during testing. After optimizing queries and adding appropriate indexes, we achieved the desired performance metrics.
