02 / 06 — Profile
End-to-end ownership of production mobile apps
I'm a Flutter developer working in a senior, self-directed capacity. Across 4+ years I've shipped 25+ applications to the Google Play Store and Apple App Store spanning HRM & payroll, billing, e-commerce, POS, SaaS, community and Islamic lifestyle products — including 4 featured products on Envato CodeCanyon.
I own a product on my own: architecture, UI/UX, development, testing and store publishing. My day-to-day runs on Dart, Firebase, RESTful APIs and scalable state management with GetX, BLoC and Provider. I write clean, documented code, fix bugs in live production apps, and work independently inside remote, cross-functional Agile teams.
- Architecture & state MVC / MVVM, GetX CLI project structure and pragmatic state management with GetX, BLoC and Provider.
- Backend & APIs RESTful API integration, Firebase (Firestore / Realtime DB), push notifications and multiple payment gateways.
- Publishing & support Independent Google Play Console and App Store Connect releases, documentation and ongoing buyer support.
- Collaboration Remote-first Agile delivery, technical documentation and mentoring junior developers.

// How I work
Architecture first, store release last.
Every app is built on a clean, testable structure with predictable state management and a typed API layer — then shipped, versioned and supported on Google Play and the App Store by the same person who designed it.
