I'm a cryptography engineer and open source maintainer. I've been in charge of cryptography and security on the Go team at Google until 2022, and was on the Cryptography team at Cloudflare until 2017. Read more about what I do and how we might know each other.
I am FiloSottile on GitHub, Twitter, and Twitch, and @firstname.lastname@example.org on Mastodon.
I attended the Recurse Center batches Fall 2013 and Fall 2 2017.
All I've written since 2013 is at words.filippo.io.
