What I'm looking for

I'm looking to build secure, scalable fintech, banking, data, or platform products with distributed teams, collaborating across product, frontend, and infrastructure to deliver reliable production-ready solutions.

I've built banking and fintech products at Stanbic IBTC Bank, including the Money Manager API and a Buy Now Pay Later platform that lets merchants receive immediate payment while customers repay in installments.

I improved EZ Cash bulk-record processing from over 25 minutes to under 6 minutes and increased loan application success by 24%. I also improved KYC onboarding feedback so customers could resolve documentation issues faster and receive functional bank accounts.

At Union Bank of Nigeria, I lead maintenance and feature delivery for Alero, a KPI and business-performance data platform, while designing ETL pipelines and reliable reporting workflows. I also build frontend products with React, Next.js, and TypeScript, including Campusrunz and BusBuzzer admin experiences.
