About

I build things for the web. I care about clean architecture, honest code, and shipping work that matters. No frameworks for the sake of frameworks. No abstractions without purpose. Just direct, maintainable software that does what it says.

Based in Seoul. Writing code since 2012. Currently interested in systems programming, developer tooling, and the intersection of design and engineering.
