What I'm looking for

I'm looking to build scalable, secure backend and data platforms where I can improve real-time analytics, cloud efficiency, API performance, and fintech system intelligence.

At Crude City Global, I lead microservices development supporting more than 10,000,000 customers while reducing infrastructure costs through cloud optimization.

I build real-time analytics and data warehousing solutions for retail and investment products, and develop core services that improve business intelligence across high-volume fintech systems. I also troubleshoot complex API integrations and performance bottlenecks while maintaining PCI DSS and financial data standards.

Previously, at Unity Bank, I built middleware data pipelines connecting bank applications with the Nigeria-Interbank Settlement System and delivered secure .NET REST APIs for corporate partners and micro-finance institutions.

Across fintech applications, I use C#, .NET, SQL Server, cloud infrastructure, microservices, CI/CD pipelines, and data orchestration to deliver secure, scalable production systems.
