# About

I build the layer around the model — sandbox, tools, evals, control plane — and publish what actually breaks. Public product engineer; demos stay on X, architecture lives here.

Ten-plus years shipping. Fortune 100 platforms (10M+ customers), GitHub Enterprise migration across 36+ repos. Osmosis Labs DevRel and engineering, early post-launch. White-hat security: DoD DC3 VDP Researcher of the Month, March 2026, for critical reports.

SpaceXAI Grokathon, August 2026: 3rd place and Most Users with ThinkVoice — Grok Voice plus sensing so people can converse without moving their mouths. On the side I ship free AI-native tools: Sub8, Xplor, GrokTerm, grok-remote, grok-bench, and more. Games are evidence of long-horizon tool use, not the pitch.

Interested in how labs eval tool use after post-training, and whether harness work lands for the team.
