Jeaye has a background in C++ systems programming, focusing on games and game engines. After 5 years of that, he co-founded an esports tournament startup written in full-stack Clojure for another 5 years. These days, he’s at Electronic Arts (EA) building tooling used to make some of the world’s top games.

In each space, C++, Rust, Clojure, NixOS, etc, Jeaye aims to make an impact with his open source projects. For Clojure, at first, that was with Orchestra. Now, the flagship is jank.

In particular, it doesn’t seem like COVID spreads via metal surfaces very much.
