01 — About

Trained on mechanical systems. Shipping intelligent ones.

I build the intelligent systems behind fintech, healthcare and creator platforms.

I started in Mechanical Engineering at the University of Lagos and ended up architecting the backends and machine learning systems that production platforms depend on. That route was not accidental: engineering taught me to model messy physical systems under constraint, and that is precisely the skill that matters when you are routing payments, matching clinicians to shifts, or ranking a video feed in real time.

Over five years I have owned full product lifecycles across six companies, from CTO at an early-stage AI startup to fraud detection infrastructure in fintech. My work concentrates on three problems: making distributed backends hold up under load, turning heterogeneous data into decisions people actually trust, and shipping models that survive contact with production.

I still publish. Three peer-reviewed papers applying machine learning to industrial systems came out of the research side of that engineering background, and it keeps the theory honest.

Model design through to production infrastructure

Five areas I work in daily — the modelling at one end, the infrastructure that has to keep it standing at the other, and the payment and platform plumbing in between.

Study builds

A structured Solidity track working through the primitives that on-chain systems are actually built from — collateralised stablecoins, token standards, verifiable randomness, upgrade proxies and trustless fund flows. Built and tested with Foundry, deployed to testnet. These are study builds rather than shipped products, and they are listed here as evidence of the ground covered.
