MORE ABOUT ME

I’m Sudhansu, a full-stack AI engineer

I build products end to end, from the database schema to the voice on the other end of the call. I care about the parts users never see: the payment that reconciles itself, the query that survives exam night, the API that hides eight messy suppliers.

I’m a final-year Computer Science student at GGSIPU, New Delhi. Off the keyboard you’ll find me at a hackathon, on a stage pitching one, or somewhere by the sea.

Most recently: Technical Intern at VARA5, building voice AI and supplier APIs for luxury travel.
