Hey! I'm currently on the Tesla AI team, where I'm working on world models for Optimus. It's wild getting to work on robots that might actually change how the world works.

Before this, I was a quantitative developer at Citadel in Fixed Income & Macro, where I got to build systematic trading systems and really fell in love with time-series data. I've also done stints at Citadel Securities working on High Performance Computing, Nuro building ML/AI infrastructure, and Salesforce making developer tools that don't make people want to pull their hair out.

I studied at Princeton and grew up in the Bay Area. When I'm not staring at code, you'll find me playing basketball, keeping way too many tabs open on market news, or yelling at the TV when the 49ers are playing.

And (as of January 4th, 2026), I've decided to start writing—which you can read here.

I genuinely love meeting new people—if you're ever in the area and want to grab coffee, hit me up!
