Ten years building fintech, healthcare and agri-tech products used by millions across Africa — from pharmaceutical supply chains to blockchain lending pools.
01
About
I'm a senior software engineer with 10 years of experience building and maintaining mobile, web, backend and blockchain-enabled applications across fintech, healthcare, agriculture, investment and counselling.
My work tends to sit where reliability matters: a pharmaceutical ordering app that 5,000+ stores depend on, a marketplace that helped distribute $2B+ in farm inputs across Nigeria, Ghana and Liberia, and a monolith I rebuilt into microservices for a 30% gain in stability and performance.
I work comfortably across the stack — React Native and React on the front, Python, PHP and Laravel services behind them — and I've led small Agile teams through backlog, delivery and post-launch stability. Alongside employment I founded AutoDistress and Faceless Counselling, which keeps me close to product decisions as well as code.
