Projects

What I build outside of work.

An agent engineering layer that lets AI coding agents work like a scoped, budgeted, reviewed and replayable engineering team.

Harness: Plan, edit and auto modes, with writes bounded to explicit file scopes
.voss: A compiled language for budgets, confidence gates, teams and review
SDKs: Local REST/SSE protocol with TypeScript, Rust and Go clients
ADE: A desktop cockpit for running agent teams
