What I'm looking for

I’m looking for a team where I can lead React Native builds end-to-end—shipping high-performance apps, strengthening security (auth/payments), and scaling architectures with clean CI/CD, strong integrations, and a product-focused engineering culture.

I’m a Senior React Native Developer with extensive experience across FinTech, Healthcare, Banking, and Cryptocurrency—focused on delivering high-performance mobile applications. I’ve built and upgraded iOS/Android products using React Native, TypeScript, Firebase, and Apollo GraphQL, with a strong emphasis on reliability, performance, and user experience.

I lead teams (including mentoring and revamps), manage complex third-party integrations, and implement secure payment and authentication solutions. From launching major apps and streamlining delivery with CI/CD to integrating Nigeria’s eNaira and health services APIs, I bring scalable architecture and execution discipline to every project.
