About
I'm a senior product designer who builds financial products for people the system was never built for. I care about making them feel clear, trustworthy, and accessible to communities mainstream finance overlooks.
Fintech is where I've spent most of my career: remittance, credit, lending, and banking for markets where trust and clarity matter most.
At LemFi I lead design for the credit suite and our next-gen design system, including extending our tooling into AI workflows so teams ship on-brand work faster.
I also host The BluePrint Series, published Road Guide to Design Systems, and mentor designers through communities like Roadtrip and HNG.
Outside design, David founded Aether Esports, a Call of Duty: Mobile organisation in Nigeria and a top T2 team in Africa.
