I'm a 24 year old systems & network engineer based in Tokyo.

I work at Railway on networking and infrastructure. Most recently, I built and deployed our new global edge network (which served this page!) from scratch using Rust, WASM and an automated self-healing control plane which controls everything from rollouts to BGP announcements. I wrote about it here:
