I build theguardrails, privacy gateways, audit trailsthat make AI safe to deploy.

A gateway that stops MCP tool poisoning. A gateway that keeps BVNs, NINs and card numbers out of prompts. Tamper-evident logs, mapped to the NDPA, GDPR and the EU AI Act. Backed by products live in production and 5+ years delivering construction to specification.

> now building: MCP Shield Gateway, Stage 2

What I build

AI security that holds up in real systems.

Built like a site is run

Five years managing construction in Lagos taught me specifications, inspections and sign-off. AI security works the same way: set the rules, check every load, keep the record, and be honest about what the checks miss.

How I work

Three principles, each with the proof.

Selected work

Built, tested, and honest about the limits.
