About

Recent UC Berkeley grad in Computer Science and Data Science, drawn to the quieter layers of the stack — distributed systems, developer tooling, and the infrastructure that has to actually hold.

My favorite hours go to long walks — once, on purpose, over a hundred thousand steps in a single day — and the slow kind of conversation that doesn't need to land anywhere. Lately I've been deep in The Pragmatic Programmer and Designing Data-Intensive Applications: the sort of books you have to put down to think. I learn most from things I can't quite name yet, and the discipline of seeing a system clearly turns out to be the same one that gets you closer to seeing anything else clearly.
