Overview

Developed a full-featured e-commerce web application from concept to deployment using the MERN stack (MongoDB, Express, React, Node.js).

Key Features

  • Product catalog with categories and search
  • User authentication (JWT) and account management
  • Shopping cart with persistent storage
  • Secure payment gateway integration
  • Admin interface for product and order management

Technologies

  • React, Node.js, Express
  • MongoDB
  • JWT for auth
  • Deployment to a managed hosting platform

Outcome

Delivered a production-ready e-commerce application demonstrating end-to-end system design, secure authentication, and payment flows.

Problem

Small merchants needed an easy way to sell products online but existing platforms were either expensive or inflexible for custom workflows.

Solution

Built a full-stack e-commerce platform that balanced a flexible product model with secure, scalable infrastructure. The platform prioritized developer productivity and merchant customization.
