Most of the screens and core logic of my FlutterFlow app are already in place; what’s missing is the solid, production-ready plumbing. I need someone who lives and breathes FlutterFlow, Firebase and Dart to step in, tie everything together, and make the build store-ready. Here is what remains: • Backend integration – The local state is working, but I still have to connect everything to Firebase properly. That includes creating the cloud Firestore structure, final indexing rules, and any remaining collections needed for production analytics. • Database setup – Migrate the current test data into its new schema, seed the initial data, and verify reads/writes from the app are efficient and secure. • API integration – I already have REST endpoints documented; your task is to wire them in FlutterFlow with proper error handling, caching where sensible, and unit tests for the critical calls. • Payments flow – The in-app purchase / subscription screen is designed, but the logic is only halfway done. You’ll finish the end-to-end payment flow (webhooks, validation, error states). • Bug fixing – A handful of UI glitches and state issues remain; you’ll track them down, resolve them, and push clean, commented commits. • Firebase cleanup – Remove obsolete functions, tighten rules, set up proper environments (dev, staging, prod) and confirm that analytics/events still fire. Deliverables: 1. Updated FlutterFlow project file with all integrations complete. 2. Clean Firebase project (FireStore, Authentication, Functions) that mirrors the implemented logic. 3. Working payments flow verified in both sandbox and production modes. 4. Short hand-off document outlining architecture choices and steps to add future features. If you have recent examples of FlutterFlow builds that are live in the stores and can jump onto a quick hand-over call, you’re exactly who I’m after. I’m ready to give you access to the repo and Firebase project as soon as we agree.
