Intro

I like building reliable systems, understanding hard problems, and spending time outside.

Currently working on Ceph, security vulnerability management, and research at the intersection of complexity, cryptography, and quantum computing.

You can usually find me with a dog, a backpack, a violin, or a terminal open.
