Computer Engineering at Purdue, class of ’28

I build backend systems, and lately the hardware underneath them. I’m an undergraduate researcher in Purdue’s CompSi group, working on RISC-V vector cores and ML accelerators. I keep things simple on purpose.

This summer I was an engineer at Paasa (YC S24), where I built services for the trading platform, an execution layer that saved the ops team 200+ hours a week, and their first FIX engine. Before that, I spent high school starting things: a health startup, a symposium for 90+ schools, and a programming contest about speed.
