TalkSphere is a full-stack, real-time chat application built as a final year college project, combining a Java Spring Boot backend with a modern React frontend. The primary challenge was developing a secure and scalable platform from scratch, which involved conceptualizing the architecture and ensuring seamless API integration. The result is a fully functional and responsive chat experience with secure authentication, real-time messaging, friend management, and privacy controls.

The backend uses Java Spring Boot with Spring Security for authentication, WebSockets (STOMP & SockJS) for messaging, and MySQL for data storage. The responsive frontend was built with React, Redux, and Tailwind CSS, and features include media sharing, emoji support, and chat themes. The system also integrates Axios for API calls and SendGrid for email notifications.
