About

Software engineer based in Singapore, I like things close to the metal Right now I'm building mra (a rust framework for building agent harnesses), and a real-time 3d graphics engine inside Emacs because apparently I can't stop making Emacs do things it wasn't supposed to do. I've also built a SQLite query engine, a Redis server in Go, a Monkey language interpreter, a bitcoin library, and a raytracer all from scratch, mostly in Rust, mostly because I wanted to understand how things actually work under the hood. If you're in SG and want to argue about whether McWings is better than McNuggets (it is), or just talk shop about systems programming, emacs, house music, or movies, book some time: calendar.notion.so/meet/ethenyiyuan/pbgpc4pgk Or just email me: [email protected]
