About
I’m Abdul Qayyum, a Flutter Mobile Developer based in Islamabad, Pakistan, focused on building production-grade cross-platform iOS and Android apps with Dart and the Flutter SDK. Over the past 1+ years, I’ve worked on integrating REST APIs and backend services, creating smooth mobile experiences with solid loading/error handling and reliable JSON data flow.
I also enjoy building data-driven and intelligent features—I’ve integrated Firebase (Auth/Firestore), MongoDB via REST APIs, and worked with AI/ML backends such as FastAPI and OpenCV in mobile frontends. My work includes OTP-based registration and approval workflows with notification support, and I’ve contributed to library and fintech-style applications end to end, from API integration to real-time updates.
