John Yoon

Engineer focused on AI enablement, agent infrastructure, evaluation, and developer tooling.

I build practical systems around AI-assisted software development: orchestrating and verifying coding agents, grounding model outputs in evidence, integrating tools through MCP, and automating developer workflows with explicit safety and recovery boundaries.
