Senior Flutter Developer for AI-Based Data Collection App (MVP)

Project Overview: I am looking for an expert Flutter developer to build a functional MVP for a data collection app on iOS and Android. The core functionality involves continuous background audio recording while capturing images and location data, which is then synced to a Firebase backend. Timeline: This is a high-priority build. I expect the core development to be completed within 7-10 days. Please only apply if you can start immediately and have experience with background services. Key Features (MVP): Authentication: Login via Google and Apple (using Firebase Auth). Background Recording: The app must record voice/audio continuously in the background (even when the screen is off or the user is navigating other apps). Simultaneous Capture: Ability to take photos without interrupting the active audio recording session. Metadata: Auto-tag photos with GPS location. Offline-First Sync: Save data locally if offline. Auto-sync audio/images to Firebase Storage and metadata to Firestore when internet is available. Dashboard: A simple view to display tabular data synced back from Firestore (processed by backend AI). Tech Stack: Frontend: Flutter (Dart). Backend: Firebase (Firestore, Cloud Functions, Storage). AI Integration: You will interface with Firestore; the actual AI processing logic (Gemini API) will be triggered via Cloud Functions (I can handle the AI logic, but you need to ensure the data structure is ready). Requirements: Proven experience with Flutter Background Services and handling iOS AVAudioSession to prevent recording interruptions. Experience with offline data caching (Hive/Isar/SQLite). Clean, modular code structure. Apply tot his job
