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

  • spine-parts — Character artwork and decomposed layers into rig-ready parts and Spine rig specs.
  • rigc — Declarative rig and animation specs into validated Spine skeleton data.
  • spine-html — Spine animations in the browser with a DOM-first renderer.
  • unity2spine — Unity 2D rigged assets converted to Spine data.

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.
