What I'm looking for

I seek senior engineering roles in fintech or digital banking where I can lead solution architecture, build secure scalable platforms, mentor teams, and deliver high-impact payments or core-banking products.

I am a Senior Full-Stack Software Engineer with over six years building high-performance fintech and digital banking platforms across leading Nigerian financial institutions. I have led architecture decisions, mentored teams, and delivered secure, scalable systems including payment switches, instant and virtual card issuance, and T24 core banking integrations.

My experience spans ASP.NET Core, C#, React, microservices, API gateways, and cloud platforms (Azure/AWS), with notable projects like corporate internet banking, digital account onboarding, payment switch middleware, and diaspora banking platforms. I prioritize secure design, operational observability, and delivery of production-ready solutions that meet enterprise compliance and performance needs.
