About
Engineer, architect, problem-solver.
I'm Michael, a Backend and Mobile App Engineer based in Lagos, Nigeria. I specialise in designing microservices architecture, event-driven systems, and high-performance APIs for fintech and logistics platforms.
Over five years, I've built production systems at companies including Access Bank, Shippack, and DasaMonie: handling real-time shipment tracking, payment processing, multi-tier KYC flows, and cloud infrastructure on AWS and Google Cloud.
On the mobile side, I build React Native apps end-to-end: from Figma-accurate UIs and biometric authentication to EAS pipelines and App Store releases. I care about clean architecture, system reliability, and shipping things that actually work.
