About Me

I like building products that people actually want to use. I've interned at Zoom working on AI features, at Alibaba Cloud on data products, and at Deloitte on backend systems — each time getting closer to understanding how good software really comes together.

I write research on the side — mostly around language models and medical imaging. A few papers came out of it, which I'm proud of.

Outside of work, I run, go to the gym, and make short videos. One somehow hit 29 million views.

Starting a master's in the U.S. this fall; final destination TBD.
