I build agent systems that actually ship -- local-first infrastructure for running coding agents: orchestration, supervision, and the runtimes that tie them together.
Went from line cook to founding GRAIsol in March 2025. Since then: ~13,000 GitHub contributions across 100+ repos, an open-source agent runtime with 1,000+ npm releases, and 12 published packages.
I don't out-type teams -- I build the tooling that lets one person ship at team scale.
| agent-afk | Open-source TypeScript coding-agent runtime/harness. ~551K LOC, 1,000+ npm releases, Apache-2.0. |
