Hi, I'm Joon

Frontend developer with 20+ years of experience, building games and tools with web technologies.

I enjoy collaborating with AI—from exploring ideas to building games and tools together.

What I'm working on

  • rig-c — A toolchain for AI-authored 2D character rigs, from layered artwork to validated animation and browser playback.

Blosharper: Battle of Blossoms

My roguelike deckbuilder based on Hwatu, Korean flower cards. Built with TypeScript, DOM, and CSS, packaged with Electron, and developed alongside AI agents.
