Production-focused Flutter Developer building enterprise, HR, B2B, POS, and operational mobile apps.
Background
How I build
I’m Abdallh elRabiey, a Flutter Developer from Cairo, Egypt, building and improving production mobile applications across enterprise, HR, medical, B2B, POS, and operational workflows.
My work focuses on building reliable, maintainable, and scalable Flutter apps using Clean Architecture, BLoC/Cubit, feature-first structures, offline-aware synchronization, secure authentication, caching, geolocation, background services, CI/CD, and production monitoring.
I have worked on apps involving attendance tracking, geofencing, selfie verification, VPN detection, device binding, POS checkout flows, supplier management, HR operations, real-time chat, encrypted caching, Socket.IO, Firebase, Fastlane, GitHub Actions, Codemagic, Shorebird, Sentry, and Firebase Crashlytics.
I care about measurable impact: reducing crash rates, improving startup time, stabilizing production apps, and making mobile codebases easier to maintain and release.
I create technical content on YouTube about Flutter, release engineering, and production stability.
