What I'm looking for

I’m looking for a remote-first team where I can lead Flutter/mobile architecture, build offline-first and secure apps, collaborate across disciplines, and keep quality high with TDD, strong testing, and automated CI/CD releases.

I’m a Senior Flutter Engineer and cross-platform mobile specialist with 5+ years of experience building production-grade apps across construction-tech, fintech, health-tech, and e-commerce. I’m known for clean architecture, BLoC/RxDart state management, and shipping secure, scalable products—consistently delivering mobile features that users can rely on.

In remote-first environments across the UK and Africa, I’ve led the design and delivery of complex Flutter applications, turning real-world workflows into reliable, user-friendly mobile tooling. I build offline-first systems with local persistence and background sync, integrate RESTful APIs and cloud services for real-time updates, and use CI/CD automation to keep releases fast and dependable.

I also contribute to open-source, recognized through Google Summer of Code 2025 with Unicode, Inc. I worked on ICU4X-powered multilingual rendering by binding Rust into Flutter via FlutterRustBridge, backed by a thorough testing strategy (unit + widget tests) to cover multilingual edge cases and ensure robust behavior under varied input.
