About Me

I’m Himadri Karan, a Full-Stack Developer from Kolkata, India. I love building web applications that blend robust backend architecture with clean, responsive frontends. I work with technologies like React, Next.js, Spring Boot, FastAPI, and PostgreSQL, and I’m deeply interested in AI integration and real-time systems.

I’m currently pursuing a B.Tech in Computer Science and Engineering (2026) at Techno Engineering College Banipur. I learn best through projects, internships, and problem-solving, continually improving my coding and system design abilities.

My goal is to grow as a software engineer by building useful, scalable, and intelligent solutions that create real impact.
