Real-Time Chat Application

• Built a full-stack real-time messaging platform (MERN + Socket.IO) featuring secure authentication, one-to-one and group chat with member management, typing indicators, and instant message delivery, backed by RESTful APIs (Node.js, Express.js, MongoDB) for scalable data persistence. • Tested and validated group chat performance with∼10 concurrent users, confirming reliable real-time message delivery and synchronization under simultaneous load. • Engineered a responsive, production-ready UI with user search, notifications, session/logout handling, and light/dark theme support — ensuring a seamless, cross-device chat experience.
