The story so far

From payments operations to the agent era.

2019
Learning how money moves
I started in payments operations at OPay: reconciliation, fraud monitoring and the daily discipline of a high-volume transaction business. It taught me that every product is, underneath, a set of rules about value.

Founding companies
I founded ComiBlock, a goal-based crypto robo-advisor that raised from Expert Dojo at a valuation of around US$3 million and grew to US$400,000 under management. Its infrastructure became my next company, Yuki: wallet infrastructure for African fintechs serving more than 20,000 API requests a day, twice through Celo Camp and into Blockchain Founders Group’s Adrenaline programme.

Leading engineering
At Circo I’m CTO and Head of Product Engineering, leading sixteen engineers whose video pipeline, protection and moderation run in production. Alongside it I built SFX’s product with its team: cross-border tuition payments now processing US$10–15 million, from a FinCEN-registered business that is a 2026 Circle grant recipient.

Building for the agent era
Now I’m building Dino, the API quality and context layer for AI agents. As agents write more of our software, they need to understand the systems they change and prove that their changes work.
