About

I'm a computer science student who learns by building. My senior capstone uses teams of AI agents to plan disaster response on real street maps, and on my own time I build tools for running AI agents, offline-first mobile apps, and games with computer opponents.

I care about software that works without fuss: apps that run offline, keep data on the device, and come with tests that prove they do what they say.
