What I'm looking for

I'm looking to lead and build secure, scalable enterprise and fintech products, owning delivery from concept to deployment while collaborating with product, QA, design, and business teams and mentoring developers.

I've built secure enterprise platforms for Ascentree Services, including a multi-tenant Practice Management System, unified identity and access services, and payroll software processing over ₦2 billion in monthly transactions.

Across Confidence Bank, MyVault Vest, Farmsquare NG, and Hoop Telecoms, I've delivered secure APIs, core banking integrations, USSD savings platforms, staff management tools, and encrypted communication systems.

I lead full-stack delivery with React, TypeScript, Laravel, PHP, Node.js, MySQL, and .NET, translating complex business requirements into production-ready systems. I've also mentored junior developers, reviewed code, and collaborated closely with product, QA, design, and business stakeholders.

As a Technical Product Lead and tutor at Cirvee, I led an in-house development team and taught multiple full-stack development cohorts.
