I break stuff and build software.

I'm currently a security developer at CoreOS. In the past I've worked for Matasano Security and GTRI doing security research and penetration testing. I've consulted on cryptographic design, reverse engineering, and scalable natural language processing. I founded a company a couple of years ago as part of YCombinator's S2013 batch and am always happy to talk to applicants.

I live in San Francisco, CA but travel frequently.

Contact me!

I would love to talk to you about crypto, tech, startups, life in the Bay Area, cooking, art projects, or anything else interesting. Don't hesitate to ask!

Got secrets? I have a GPG key which can be verified at keybase.io.
