What I'm looking for

I’m looking for a senior Flutter/mobile role where I can architect NFC/offline-first features, lead clean, SOLID codebases, optimize performance, and ship reliably with strong CI/CD and mentorship in an Agile fintech or e-commerce team.

I’m a Senior Flutter Developer and cross-platform mobile architect with 5+ years of experience delivering “high-performance, jank-free” mobile apps for fintech and e-commerce. I focus on Clean Architecture and SOLID principles to build scalable, maintainable codebases that teams can move fast with confidence.

I’ve spearheaded NFC-enabled payment platforms and offline-first data sync solutions, boosting transaction throughput by 40% and user adoption by 25%. At Swwipe Financial Services, I led end-to-end Flutter architecture and development, launching production-ready POS experiences and reducing transactional failures by 30% across retail clients.

I’m also a performance-and-quality minded engineer: I use Flutter DevTools for profiling, apply TDD (unit, widget, integration), and implement CI/CD automation with GitHub Actions, Codemagic, and Fastlane. Through analytics-driven iteration with MixPanel, I improved engagement metrics by 35% and kept release defects under 3% using code review protocols and disciplined architecture.

Beyond shipping features, I thrive on collaboration and mentorship. From Sterling Bank and Zummit Africa to earlier full-stack and cybersecurity work, I’ve supported Agile delivery, refactored legacy systems (MVVM, state management with Stacked/Riverpod/BLoC), migrated to null safety and Flutter 2.0, and consistently improved stability, launch times, and developer onboarding.
