What I'm looking for

I'm looking to build secure, compliant banking, payments, or investment products where I can own React or React Native delivery, contribute to Django APIs, and improve transaction performance and reliability.

I've built and scaled fintech web and mobile products for Systemspecs' Monicenta, Stanbic IBTC Fintech's Zest Payment Platform, and VFD Microfinance Bank. My work covers secure fund transfers, reconciliation, escrow, wallet top-ups, investment flows, and KYC onboarding.

At Systemspecs, I designed real-time transaction and reconciliation modules, established TDD and GitHub Actions CI/CD practices, and led performance work that improved system response time by 30%. I've also optimized fund-tracking experiences with SSR and lazy loading, while partnering with product and compliance teams on API security and financial standards.

I'm currently shipping Vella's housekeeper marketplace app end-to-end, owning its React Native frontend and Django REST backend. I use Claude Code and Cursor to accelerate implementation, debugging, and review without compromising code quality.
