kazeem Asiwaju-Bello

I've delivered cloud-native banking, fintech, SaaS, and AI platforms across Naviri, GitStart, Union Bank of Nigeria, Precise Financial Systems, and AXA Mansard Insurance. I build backend-leaning full-stack systems with C#/.NET, Node.js, NestJS, React, Angular, and API-first microservices.

At Union Bank, I led a zero-downtime FCUBS v12 to v14 core banking migration for millions of customers and designed Open Banking services spanning payments, card services, and complaints handling. I also led eight engineers building an enterprise CRM and complaint-management system that reduced resolution time by 40%.

At GitStart, I reduced API latency by 45% through caching, indexing, and asynchronous processing, while improving test coverage by more than 30%. I also introduced Docker and GitHub Actions delivery workflows; at Union Bank, Docker and Jenkins pipelines cut deployment cycle time by 40% and a multi-cloud strategy reduced infrastructure costs by 25%.

I'm comfortable owning architecture through production support, communicating trade-offs across technical and business teams, and mentoring engineers. I bring TOGAF Enterprise Architecture training, multi-cloud experience across AWS, Azure, and GCP, and ongoing hands-on exploration of agentic AI tooling in the software development lifecycle.
