About
I’m a software engineer in San Francisco interested in developer tooling, low-level systems, AI, cryptography, and programming language design.
I’m currently helping Claude run faster at Anthropic. Most recently, I was a founding engineer of Eclipse and cofounded a startup backed by Hyper. Previously, I did engineering at Jane Street and Dropbox.
I graduated from UC Berkeley where I studied electrical engineering and computer science, as well as applied math.
