Thomas Underhill will teach you to ship AI you can prove works

I build and operate AI systems in places where you have to prove things: that the data never left, that the model did what you say, that a person approved the action.

Constellation is a self-hosted platform I architect and maintain: authorization on every tool call, pluggable secrets and sandboxing, a tamper-evident audit trail, local inference, sealed and air-gapped by default. My research is on evaluation that cannot be gamed by whoever benefits from the score.

Twenty five years in enterprise software before that, in senior roles at PayPal, Oracle, VMware, HashiCorp, F5 and AWS, running SOC 2, PCI-DSS, FedRAMP and NIST 800-53 as engineering programs, not paperwork. Nine years as adjunct faculty at universities. U.S. patent. J.D. Startups.

Everything I teach, I have had to make work first.
