I'm looking for a talented Android app developer who can implement a feature into an existing app that saves various types of data locally for later uploading when the device reconnects to the internet. The types of data include text, images, and videos. Make the app available offline by storing data locally. Currently, the class /mobile_app/src/db/classes/[login to view URL] is used to save ticket information in SQLite, but this may not be the best approach. Storing the data in a JSON file would likely be more efficient and easier to manage. The app should automatically send any unsynced data to the backend when an internet connection becomes available. Use an Expo or React Native API to handle this functionality Key Requirements: - Proficient in Android app development - Experience with local storage and data upload management - Ability to program automatic uploads triggered by internet connectivity I'm expecting a seamless user experience with no need for manual intervention. If you have relevant experience and can deliver high-quality work, I look forward to your bid.

Hello, Offline Data Storage Enhancement in React Native App We propose a solution to improve the offline capabilities of your React Native app by transitioning from SQLite to JSON-based local storage. This enhancement will ensure data persistence and automatic syncing with the backend when connectivity is restored, streamlining ticket management and user experience. Approach: Offline Data Storage: Transition ticket information from SQLite to JSON storage for easier data handling. Implement secure and efficient JSON storage using Expo or React Native's AsyncStorage API, ensuring fast local access. Data Syncing Mechanism: Develop functionality to automatically detect internet availability and sync unsent data to the backend. Implement a queue system for pending data to prevent loss during outages and maintain data integrity. Technical Stack Integration: Backend: Use FastAPI, Alembic, SQLAlchemy, and MariaDB to ensure seamless database integration. Mobile: Utilize React Native with Expo and Tailwind (Nativewind) for a consistent user interface across platforms. Firebase: Integrate Firebase/Google Cloud for optional cloud sync and notification management. Thanks & regards Julian
