About

Hi — I'm Junyoung Ryu (Jun0). I work in Applied ML and Statistics out of Seoul, Korea.

I find what others miss in AI — then build it or fix it. Most of my recent work sits at the seam between agent systems and the humans who try to trust them: why agents fail quietly, why users stop checking, and what an honest verification layer looks like in practice.

Currently building

  • sonmat — Claude Code plugin that builds verification habits into AI–human collaboration.
  • bobusang — Multi-device memory system for Claude Code via git-based auto-sync.
  • clance — Lightweight Tauri-based system monitor — CPU, memory, GPU, processes at a glance.
