CampusMart is a full-stack MERN web application built to enable college students to buy, sell, and trade items within their campus community. The platform allows users to create listings, view available products, update item details, and remove listings when items are sold. I implemented complete CRUD functionality with a focus on clean architecture, smooth user experience, and responsive design. The frontend is developed using React.js and Tailwind CSS for a modern, mobile-friendly interface, while the backend is powered by Node.js and Express.js with MongoDB for data storage. The project follows a structured API-based approach for handling client-server communication. Key features: • Full CRUD operations (Create, Read, Update, Delete) • RESTful APIs for product management • Responsive and user-friendly UI • MongoDB database integration • End-to-end MERN stack implementation This project strengthened my understanding of full-stack development, REST APIs, database operations, and real-world application workflows.
