Hi, I'm
Nishan
I'm a full-stack developer and AI engineer based in Kolkata. I build production backends and AI-powered products end-to-end — from Next.js interfaces to FastAPI services and Gemini integrations. I built ShipIntern, an internship-finding tool for fellow students that reached 250+ users.

Developing since 2023 — now in final year of college.
