About

I study Computer Science (Data Science) at VIT Vellore and Data Science at IIT Madras.

I like owning things end to end: the interface people see, the service behind it, and the servers it runs on.

My work runs where people depend on it. Papers serves exam papers to 134K+ students. FFCS-inator plans timetables for 30K+.

Right now I work as a junior software engineer at 797th LLC and lead the infrastructure for VCAP at VIT.
