About

Thirteen months from first commit to production payment flows.

Cofounder and CTO at Codedevs, building production web and AI products from Lagos — escrow-backed payments, WhatsApp commerce, and AI agents that show their reasoning before they act. Four hackathon podiums, including first place at the Africa's Talking BuildWithAI Pan-African finals.

How I got here

I started writing code in August 2025. Thirteen months later I was shipping subscription billing against a live payment provider, a WhatsApp commerce channel driven by model function calling, and the escrow and dispute flows that decide whether a stranger's money is safe.

That slope is the most honest thing I can tell you about how I work. I learn by building something that has to survive contact with a real constraint — a telecom protocol that only allows short sessions, a payment webhook that arrives twice, a buyer who has no reason to trust a seller they found in a feed.

I build for the environment I am actually in. Bandwidth drops, devices are limited, and a lot of commerce runs over WhatsApp rather than a web app. Designing for that is not a limitation to apologise for; it is the interesting part of the problem.

I am 16, based in Lagos, Nigeria, and working while preparing for university. I mention it because it is the context for everything above, not because it should change how the work is judged.
