about / 소개

I'm Yongjoon. I write software that is mostly small and occasionally finished. I prefer plaintext to dashboards, terminals to IDEs, and notebooks to project-management tools.

By day I work on tooling for other developers. By night I read essays about light, look at old code as if it were calligraphy, and break things on purpose.

You can reach me. The glitch is, occasionally, the signal.
