I'm Sueun, but everyone calls me Zoe. Born in Korea, raised in the States, now building things in Japan.

Frontend and SRE, now in developer tooling. I work on the tools and workflows other engineers build with, which puts most of my days somewhere between a React component and a CI pipeline. The SRE years stuck: I think about reliability and observability while building, not after.

I love a good writing collaboration, especially the kind where I put a tool through a real project and write up honestly how it went.
