We need to migrate our mobile application from Flutter to React Native to align with our web application, which is built with React. This will allow for a more efficient and unified codebase across both platforms. Additionally, we will transition our backend services from Firebase to AWS and MongoDB.

Current Setup:

• Mobile App: Built with Flutter, using BLoC for state management (complex to decouple).

• Web App: Built with React, hosted on AWS Amplify.

• Backend: Currently on Firebase.

Objective:

• Convert the existing web app into a React Native mobile app to share most of the codebase.

• Implement AWS and MongoDB as the new backend solution.

Scope of Work:

1. Mobile App Migration:

   • Recreate the existing mobile app functionality in React Native using the same logic as the React web app.

   • Ensure smooth UX and feature parity with the current Flutter app.

   • Optimize performance for mobile devices.

2. Backend Migration:

   • Replace Firebase with AWS services and MongoDB.

   • Implement authentication, database, and API integrations in AWS.

   • Ensure data migration and security best practices.

3. Codebase Unification:

   • Refactor components and logic to maximize code sharing between React web and React Native.

   • Implement efficient state management in React Native (consider Redux, Recoil, or Context API).

Resources:

• Current Mobile App: scheduler-systems.com

• Current Web App: Amplify Hosted Web App

Deliverables:

• Fully functional React Native app matching current Flutter app features.

• AWS & MongoDB backend integrated with both mobile and web apps.

• Documentation on setup, deployment, and maintenance.

Acceptance Criteria:

• Mobile app is fully migrated and functional on both iOS and Android.

• Web and mobile apps share a unified codebase with minimal duplication.

• Backend services successfully transitioned to AWS & MongoDB.

• Comprehensive testing is completed, including unit, integration, and end-to-end tests.
