Application security and DevSecOps engineer with a pentester's background. I build security into the delivery pipeline — threat modeling, SAST and DAST, secure SDLC — and I have spent years on the offensive side, testing web, mobile and cloud targets. On the cloud side I work with IAM across AWS and Azure, leaning on short-lived credentials instead of static secrets so access stays auditable.

Most recently I have been working on the security of AI agent systems: colmena, my open-source trust firewall, applies deterministic per-agent policy to every tool call a coding agent makes, with no model in the hot path.
