I build secure learning architectures for AI agent systems so they safely improve over time. The learning side is qortex (adaptive retrieval) and buildlog (a measurable feedback loop that teaches coding agents to suck less). The security side is threat models, sandbox architectures, and exploit research. The gap between "the code works" and "the system is safe" is what I do for a living.

Currently: consulting on agent architecture, AI security audits, and production observability. Building LinWheel (agent-native LinkedIn publishing with per-user voice learning), qortex, and buildlog. Same adaptive learning engine behind all three.

Previously: Principal Engineer at 2U/edX, where I built the sandbox platform behind their $80MM+ ARR Cybersecurity Bootcamp. First full-time Curriculum Engineer at Trilogy Education before the $750M acquisition. Technical writer at Scotch.io, Tuts+, DigitalOcean. I've been explaining hard things clearly for a decade. Now I build them, too.

Some of the writing on this site is co-authored with Claude. They handle code archaeology, structural drafts, and adversarial review. I handle narrative, voice, and editorial judgment. The author notes on each article say who did what.

I study Old Norse for fun. The sagas are better than most of what this industry publishes.
