Field notes on making agents work in the real world.

I'm starting to publish what I've learned building agentic systems inside mission-critical airline IT — on reliability, security, and the economics of going agent-native. Here's what's on the way. Follow along on LinkedIn while these land.

Securing agents that act with real permissions

As agents gain tool access, the security surface changes. A Certified Ethical Hacker's view on governing autonomous systems.

Governance

The agent governance gap: who is accountable when an autonomous system acts?

Audit trails, human-in-the-loop, and the accountability model regulated enterprises need before they let an agent touch production.

Coming soon
Enterprise AI

Why regulated enterprises stall on AI — and the pattern that unsticks them

Procurement, risk, and compliance kill most enterprise AI before it ships. The adoption path that gets past the pilot without cutting corners.

Architecture

Grounding agents in enterprise knowledge: why retrieval alone isn't enough

Knowledge graphs, governed context, and the retrieval architecture that keeps agents accurate against a company's real, messy source of truth.
