Yeachan Heo

Yeachan Heo, a developer based in Seoul with around 4,800 GitHub followers, publishes his best-known project, oh-my-claudecode: a multi-agent orchestration system for Claude Code with more than 39,000 stars, designed to help teams run multiple AI agents in coordination rather than in isolation from each other.

A comparable sibling project, oh-my-codex, applies the same approach to OpenAI's Codex, adding hooks, agent teams, and status displays (HUDs). Heo describes his own working style as "mass-vibe-code with Claude" and is also associated with @Layoff-Labs, an organization whose self-description centers on AI-driven automation in research and development contexts.

Beyond multi-agent systems, his focus also includes quantitative (algorithmic) trading — a combination that shows up in other projects too, such as clawhip, a Rust-based event router for managing notifications in automated systems.
