Architecture
Defensible systems.
The failure mode of most enterprise software isn't scale, it's complexity and access control. I build append-only trails, strict role boundaries, and deterministic policy gates that hold up under audit.
Zero-Trust Agent Runtimes
Building AI systems that refuse to execute state changes unless authorized by deterministic policy engines and observed environment verification.
Public Sector Scale
End-to-end applications designed for peak load, not the comfortable average. If it breaks during an election, it fails the city.
