About this gig

Hi, I'm Karan, a Computer Science student at Chandigarh University with hands-on experience in full-stack web development. I specialize in building web applications using the MERN stack (MongoDB, Express, React, Node.js) and Java/Spring Boot backends.


I've completed 30+ certifications including courses on REST APIs, Node.js, React, Spring Boot, SQL/NoSQL databases, and software engineering practices from platforms like LinkedIn Learning, IBM, and NPTEL (IIT Madras). I also practice data structures and algorithms regularly on LeetCode and HackerRank, which helps me write efficient, clean code.


What I offer:

- Full-stack web applications (frontend + backend + database)

- REST API development and integration

- Bug fixes and performance optimization

- Responsive, modern UI with React

- Secure backend development with Spring Boot or Node.js/Express


I'm committed to clear communication, timely delivery, and writing well-documented, maintainable code. Let's discuss your project and build something great together!
