I've built a real-time MERN chat application featuring one-to-one messaging, authentication, file sharing, channels, and persistent chat history using React.js, Node.js, Express.js, Socket.IO, and MongoDB.

I designed RESTful modules for authentication, contacts, messages, and channels, organized the backend with MVC architecture, and implemented JWT-protected routes for concurrent users through persistent WebSocket connections.

I also developed an Ethereum-based drug supply chain DApp using React, Web3.js, MetaMask, and Ganache. The application supports five stakeholder modules and enables end-to-end medicine traceability from manufacturing to retail distribution.

I'm pursuing a Master of Computer Application at Delhi University and bring hands-on experience in Java, Python, JavaScript, SQL, data structures, algorithms, databases, and full-stack web development.
