About

MERN Full Stack Developer with hands-on experience building production-grade web applications from database to UI. I architect and ship features across the full stack — designing RESTful APIs in Node.js + Express, managing data in MongoDB, and building responsive, component-driven interfaces in React.js.During my internship at Precursor Info Solution, I worked on live client projects — contributing to both backend logic and frontend delivery, writing clean, maintainable code under real deadlines. I also completed a software development internship at CodSoft, further sharpening my development fundamentals.I independently built RentHive — a full-stack rental property platform with JWT-based authentication, role-based access control, RESTful API integration, and optimized React state management. It is not a tutorial clone — it solves a real workflow problem, end to end.What drives me: writing code that scales, debugging what others overlook, and owning features from architecture to deployment. Currently seeking a Full Stack Developer role in an IT company where I can ship meaningful product and grow fast.Stack: MongoDB · Express.js · React.js · Node.js · REST APIs · JWT · Git · Postman · VS Code

React.js · Node.js · Express.js · MongoDB · Socket.io • Built a real-time messaging system using Socket.io, delivering message delivery latency under 100ms in local tests. • Developed 20+ REST API endpoints covering posts, likes, comments, follows, and direct messages — fully documented via Postman. • Implemented scalable event-driven backend architecture enabling concurrent connections without performance degradation

Connexta(E2E Chatting Application)

This project is a real-time chatting web application that allows users to communicate securely with each other. The application uses end-to-end encryption (E2E), which means that messages are encrypted on the sender’s side and can only be decrypted by the receiver. Even the server cannot read the messages. The system provides a smooth and secure communication experience similar to modern messaging platforms.
