I'm a cryptography and software engineer. I do cryptography and security on the Go team at Google. Read more about what I do and how we might know each other.

The GitHub account is @FiloSottile. The Twitter handle is also @FiloSottile.

My most popular project is mkcert. The one I have the highest hopes for is age.

I attended the Recurse Center batches Fall 2013 and Fall 2 2017.
