01 · Agent security
Guardrails between AI agents and their tools
A gateway that scans tools for hidden orders, pins the approved ones, checks every call against policy and asks a person before data leaves.
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.

What I build
AI security that holds up in real systems.
02 · Privacy engineering
Personal data stays out of the prompt
Redaction gateways, on-device processing and logs that record counts, not values. Built for Nigerian identifiers: BVN, NIN, phone and card numbers.
03 · AI governance
Controls you can run, mapped to the rules
The NDPA 2023, GDPR and the EU AI Act turned into working controls, a one page AI policy and staff training.
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.
Note 1
Scope before building
Work out what done means before anything gets poured or coded.
Note 2
Build in checks
Assume things will go wrong, and make the system catch them.
Note 3
Hand over working
It only counts once the owner is running it without me.
Selected work
Built, tested, and honest about the limits.

MCP Shield Gateway
A security gateway between an AI assistant and its MCP tools. It scans every tool for hidden orders, pins the approved ones, checks every call and keeps a tamper-evident log.

PII Swapping Gateway
Swaps personal data (BVN, NIN, phone, card and email) for random tokens before a prompt leaves for an outside AI model, then puts the real values back in the reply.
- Python 3.10+
- Zero dependencies
- HMAC-SHA256
- unittest
- Anthropic API (optional)

AI Governance for Nigerian SMEs
The NDPA 2023 and the EU AI Act, turned into controls a small business can run on Monday: risk tiers, keeping personal data out of prompts, guarding AI agents, and a 90 day starter plan.
