FlutterFlow App Takeover, Figma Redesign, Paywall and App Store Launch

I’m seeking an experienced FlutterFlow developer with strong Figma/UI-UX design skills to take over an existing AAC support app currently built in FlutterFlow with Firebase and available in TestFlight. This is an existing app, not a rebuild. Work should be completed within the current FlutterFlow/Firebase project unless a change is specifically discussed and approved. The project includes: * Auditing the existing FlutterFlow build and identifying layout, navigation, responsiveness, and technical issues * Redesigning/refining the interface in Figma * Implementing the approved design in FlutterFlow * Preserving the existing content, functionality, and backend architecture while implementing approved design and functional changes * Correcting navigation and layout problems * Ensuring the app works well across supported iPhone screen sizes * Ensuring screens remain usable when users increase iOS text size/accessibility settings, including expanding and scrolling appropriately rather than clipping, overlapping, or breaking * Implementing and testing an in-app subscription/paywall * Completing thorough QA * Preparing the app for App Store launch * Providing post-launch bug support and maintenance as needed Applicants must have experience taking over partially completed FlutterFlow projects, working with Firebase, creating polished mobile interfaces, implementing in-app subscriptions, troubleshooting iOS layout behavior, and supporting apps through launch. Please include links to relevant FlutterFlow apps and Figma designs you personally completed, and clearly describe your role in each project. All project work, code, designs, backend configuration, and related assets must remain accessible to the client in client-owned accounts and projects. Development should not be moved into private repositories, accounts, or other systems without prior approval.
