Hi, I'm John 👋

I'm the Chief Information Security Officer at GoFundMe, where we help people help each other. I work in security and still write a lot of code, mostly cryptography and infrastructure tooling. I'm also on the Gleam core team.

What I build:

  • 🔒 Cryptography libraries for Gleam: kryptos, gose (JOSE/COSE), and glasskey (Passkey/WebAuthn)
  • 📡 tsbridge, for running multiple HTTPS services on a Tailnet
  • 📜 ACME (Let's Encrypt) clients: acumen for Gleam and ex_acme for Elixir

Outside of work, I volunteer for the Dystonia Medical Research Foundation 🧠
