Real-time Chat Application

he Real-Time Chat Application is a secure and efficient communication platform designed for seamless messaging between users in various environments, such as personal, professional, or community settings. The application supports real-time messaging, user authentication, and message history, providing a reliable and responsive communication tool. It leverages Node.js, Express.js, WebSocket for real-time communication, MongoDB for database management, and SonarQube for code quality assurance.

My Role and Contributions

As a developer on this project, I was responsible for the end-to-end backend development and system optimization. My key contributions included:

Backend Development:

Node.js & Express.js: Designed and implemented the backend using Node.js and Express.js, ensuring a robust and scalable architecture to handle real-time messaging.

WebSocket Integration: Integrated WebSocket to enable real-time, bidirectional communication between clients and the server.

API Creation:

Developed secure RESTful APIs for user authentication, message sending, and retrieval.

Ensured APIs were well-documented and easy to integrate with various frontend clients.

Database Management:

MongoDB & Mongoose: Designed the database schema and managed data storage using MongoDB. Utilized Mongoose for efficient data modeling and interaction.

Implemented features like message history, user profiles, and conversation threads.

Real-Time Features:

Implemented real-time notifications for new messages and user status updates (online/offline).

Ensured the application could handle high concurrency with efficient resource management.
