the full-stack developer of this jewelry e-commerce platform, I built the entire system using the MERN stack to ensure performance, scalability, and a modern user experience. On the frontend, I used React.js to create a responsive, elegant, and interactive UI where users can easily browse collections, filter products, add to cart/wishlist, and complete secure checkouts. On the backend, I built a robust Node.js and Express.js server to handle API requests, user authentication, order management, and secure admin operations.
