I build high-performance React Native fintech and real-time mobile products.

Nigeria

Message

I've shipped mobile products for GTBank, Haliso Group, TeraWork/OmniRetail, and DeliveryWe, building banking, payments, retail, and real-time logistics experiences for iOS and Android.

At Haliso Group, I built payment microservices processing 800+ daily transactions across 60+ merchants, improved throughput by 40%, and sustained 99.6% API uptime. At GTBank, I architected scalable React Native and Expo UI foundations, type-safe API integrations across 40+ endpoints, bill payments, transfers, and E2E coverage for critical banking flows.

I work end to end across React Native, Expo, TypeScript, Node.js, Cloudflare Workers, and real-time systems. I've also published an open-source React Native OCR package using TurboModules, Vision Camera, and on-device ML inference.
