Profile README

I'm currently a ~~software engineer~~microkitchen inspector at Meta, working on Pyrefly (our next-gen typechecker for Python). Previously, I worked on developer infrastructure for WhatsApp and product infrastructure for Messenger.

I'm interested in compilers, programming languages, and data visualization, and I maintain a blog where I talk about some of those things.
