I'm looking for an experienced mobile app developer to either migrate my current Flutter-based app to React Native or Cordova/Ionic, or to make it more efficient with a few enhancements. The aim is to make the code manageable for future upgrades. Key Requirements: - Add new features: - Real-time data updates - Push notifications - User authentication - Optimize the existing code for better performance and easier maintenance - Ensure the UI is capable of managing/testing hardware by sending commands The backend support for these new features is already fully developed, so the focus will primarily be on the app's migration and enhancement. The ideal freelancer for this project should have a strong background in mobile app development, particularly with React Native and Cordova/Ionic, and be able to deliver a high-quality, efficient product. The primary reason for the switch is performance issues with the current Flutter-based app. Preference for migration is React Native. The project should be completed within 1 month. Minimal UI/UX changes should be applied to the app. The new features should be integrated using a modular approach. Ensure the app supports both iOS and Android. The app should be optimized for Android. Focus on both migrating the existing code to React Native/Cordova/Ionic and implementing enhancements as described. The migration should be to React Native. The current Flutter-based app has slow loading times that need to be addressed during the migration and enhancement.

HOPE YOU CAN FIND THIS MESSAGE WELL! Dear client, I have over 6 years of experience with Flutter and React Native. I have migrated several times React native apps to flutter. If the flutter app has problems with speed and features, it is architecture problem to manage states and process. After checking the code, I can update the app without migration to React Native. In many cases, Flutter is better than React Native. For three weeks, I can enhance the flutter app and implement necessary features including notification, real-time updating, authentication, and others. I am prepared to start the development now. I look forward to working with you. Best regards, Eric
