Problem Statement
The challenge we set out to solve

I wanted to build a real-time chat app from scratch to better understand how sockets, authentication, and full-stack architecture work together. Most tutorials focus on isolated parts, so I created Connect-chatApp as a complete project that handles messaging, authentication, and responsiveness in one place.

Project Description

Connect-chatApp is a real-time messaging platform built with the MERN stack and Socket.io. It supports both private and group chats, with message persistence in MongoDB and secure JWT-based authentication. The responsive interface, styled with Tailwind CSS, delivers a smooth experience across devices.

Group chat functionality includes role-based access control, where only the group admin has the ability to add or remove members. This feature was implemented to explore permission management in collaborative environments. This project was built as a personal challenge to understand real-time communication, full-stack architecture, and user authentication in a hands-on way.
