I’m a results-driven Senior Backend and Mobile Engineer with over 7 years of experience building scalable fintech, e-commerce, enterprise, and mobile-first platforms across Africa and Asia. My focus is backend architecture, RESTful API development, and technical leadership that helps teams deliver reliably.

In my recent roles, I architected scalable backend systems for high-volume fintech and gift card transactions, designed and deployed RESTful APIs for 10,000+ monthly active users, and reduced transaction failure rates by 35% through payment flow optimization. I also integrated Stripe, Flutterwave, and Paystack for multi-region payment processing, while establishing secure coding standards.

I bring end-to-end delivery across web and mobile, from planning to deployment—shaping secure JWT authentication, role-based access control, and mobile-first architectures that increased user engagement by 50%. I also lead enterprise innovation and research work, defining technical strategy and delivering systems that reduced operational inefficiencies by 30%.
