01 / About

It started with sports.

I’m Aamodit Acharya, a Statistics graduate from the University of Waterloo. I like messy problems, good people, and the point where a bunch of scattered ideas finally starts making sense.

Currently: Applied Scientist at Ramp, working full-time on financial intelligence and reporting.

My story started with arguing with friends about sports: hockey takes, F1 calls, and debates that needed more than vibes. I started pulling data, finding patterns, and using insights to prove them wrong. Somewhere in that chaos, I realized I liked turning messy questions into cleaner answers.
