About Me

I'm a passionate Full-Stack Web Developer and Computer Science student at Bipin Tripathi Kumaon Institute of Technology, Dwarahat, with hands-on experience building modern web applications.

I specialize in the MERN stack — MongoDB, Express, React, and Node.js — crafting responsive, performant full-stack applications from end to end. I love turning ideas into polished, production-ready products.

Beyond web development, I also explore AI/ML and NLP, building tools like semantic search pipelines and emotion analysis dashboards that bring cutting-edge ML research into practical applications.
