The mind
behind
the code

I'm a B.Tech Graduate in Artificial Intelligence & Data Science with hands-on experience across machine learning, gen AI, and full-stack web development.

I've shipped real products — from an RAG-based document QA pipeline deployed on the cloud, to a Blog-site. Based in Thanjavur, Tamil Nadu. Open to remote and on-site opportunities.
