I have a flutter app frontend and admin panel that needs a backend developer to complete the setup. The necessary backend functionalities include user authentication and database integration. - User Authentication: Implement a secure and efficient user authentication system to manage user registrations, logins, and sessions. - Database Integration: Set up a robust database solution to handle app data. (Note: Preferred database technology was not specified, so flexibility is key) Additionally, the backend needs to integrate with: - Payment Gateway: Implement a reliable and secure payment gateway for processing transactions. - Firebase: Set up and integrate Firebase for real-time data sync and notifications. Ideal candidates for this project should have extensive experience with backend development, especially with Flutter apps. Proficiency in setting up user authentication systems and integrating databases is crucial. Previous experience with implementing payment gateways and working with Firebase will be highly advantageous. Strong understanding and flexibility with various database technologies will be appreciated, as the preferred tech was not specified.
