I've been building Flutter apps since the public beta in 2018, back when half the packages didn't exist yet and you had to write a lot of things yourself. That background means I don't just know how to use Flutter; I understand why it works the way it does, and how to get the most out of it when a project gets complex. Over the past 10 years I've shipped 40+ cross-platform iOS and Android apps across fintech, healthcare, e-commerce, and enterprise, everything from solo builds to leading teams of 8+ developers. Some of those apps are sitting at millions of active users right now. STATE MANAGEMENT & ARCHITECTURE I work primarily with BLoC / Cubit for enterprise-scale apps, Riverpod for modern reactive setups, and GetX or Provider for lighter projects. I don't have a religion about state management, I pick what fits the project. On the architecture side, I follow Clean Architecture with feature-first modular structure, Repository Pattern, and proper dependency injection using GetIt or Injectable. MVVM and DDD where the domain complexity warrants it. FLUTTER & DART CORE Flutter SDK 3.x, Dart 3.x with full Null Safety. I'm comfortable deep in the framework, CustomPainter, RenderObjects, Slivers, Platform Channels (MethodChannel, EventChannel), Dart Isolates for heavy computation, and Flutter DevTools for performance profiling. Navigation with GoRouter or AutoRoute. Animations from Hero and Tween through to Rive and Lottie. FIREBASE & BACKEND INTEGRATION Firestore, Realtime Database, Firebase Auth, FCM push notifications, Remote Config, A/B Testing, Crashlytics, and Cloud Functions. For APIs: Dio with Retrofit is my standard, graphql_flutter or Ferry for GraphQL, and socket_io_client or web_socket_channel for real-time. I've also integrated Supabase, AWS Amplify, and Appwrite on various projects. PAYMENTS, MAPS & THIRD-PARTY SDKs Stripe (flutter_stripe), In-App Purchase with RevenueCat, Google Maps and flutter_map, Agora and Twilio for real-time voice/video, and analytics via Mixpanel, Amplitude, and Firebase Analytics. LOCAL STORAGE & OFFLINE-FIRST Hive and Isar for fast local NoSQL, sqflite and Drift for relational data, flutter_secure_storage for sensitive data. I architect offline-first where needed, local cache, background sync, conflict resolution. TESTING & CI/CD Unit, widget, and integration testing with flutter_test, Mockito, and Mocktail. Golden tests for UI regression. For CI/CD I use Codemagic (Flutter-native, preferred), Fastlane, GitHub Actions, and Bitrise. Delivery via TestFlight and Google Play tracks, staging through Firebase App Distribution. UI & DESIGN HANDOFF Pixel-perfect Figma to Flutter with responsive and adaptive layouts using LayoutBuilder and MediaQuery. Material 3 (Material You), Cupertino widgets, dynamic theming, dark mode, and accessibility with Semantics. Also fluent in FlutterFlow for rapid prototyping with custom code injection. One thing clients mention consistently: I communicate clearly and early, not just when something is done, but when something needs a decision or looks like it could become a problem. That kind of transparency tends to make projects go smoother. If you have a Flutter project, whether it's greenfield, a rescue, or needs a senior hand on an existing codebase, I'm happy to have a quick call and tell you honestly what it would take.
