At Homoluz, I led Flutter development of Cashflow, a mobile money app live on iOS and Android. I built its payment flows, QR scan-to-pay, and biometric and device-PIN authentication.
I also built the transaction reconciliation flow for MTN MoMo and Orange Money, using Firestore to keep payer and merchant up to date as payments settled. For Paymatch, I paired a Flutter client with an Express.js and TypeScript backend.
At Dohtech Solutions, I built Buzme and Buzme Delivery, including voice and video calling with WebRTC and real-time courier tracking. I also built web apps for the Buzme products and led one engineer on delivery of the tracking feature.
My work spans mobile, web, and backend products across fintech, logistics, healthcare, and education. I built Lewah, a personal education platform with streaming AI feedback and offline-first mobile caching, and supported data preparation and model training workflows for the DSI-Africa CHD AI project.
