Naeem U.

Flutter Developer with 8 years of building production iOS & Android apps, specializing in apps that connect to hardware or sync data in real time: Bluetooth/BLE device pairing, IoT integration, live location tracking, and offline-first sync. Started as a native Android developer, moved into Flutter early, so I bring native platform depth (Kotlin, Swift, Java) plus Flutter's cross-platform speed to every build. RECENT WORK: 1-Supervised-release monitoring app: BLE device pairing, live GPS tracking, automated check-ins, cloud backend 2-Property management platform: real-time listings, cloud database, multi-user sync 3-E-commerce and parking/IoT apps: payment integration, hardware-to-app communication WHAT I HANDLE END-TO-END: ✅ MVP development: Figma/design files to published App Store & Play Store app ✅ Bluetooth & IoT integration: device pairing, real-time hardware sync ✅ Firebase / cloud backend: Auth, Firestore, push notifications, analytics ✅ REST API & WebSocket integration ✅ Payment gateways & in-app purchases ✅ Offline-first apps: local storage (Hive, SQLite) with cloud sync ✅ State management: BLoC, Riverpod, Provider, GetX ✅ Performance fixes, refactoring, and legacy codebase cleanup ✅ App Store / Play Store release management TECH STACK: Flutter, Dart, Kotlin, Swift, Java, Firebase, REST APIs, WebSockets, Bluetooth/BLE, GPS/location services, SQLite, Hive, BLoC, Riverpod, Provider, GetX, CI/CD (GitLab, TestFlight, Play Console) Top Rated Plus on Upwork. Former "Best Android Developer of the Year" (previous company). I've also led dev teams, not just written solo code, so I can scope realistically and communicate clearly on timelines. If your project involves connecting an app to a device, a real-time backend, or both, send me an invite and I'll take a look.
