I’m part-way through a cross-platform project that already has a Python FastAPI backend and a Flutter mobile interface. The next milestone is to finish wiring these layers to Firebase’s Realtime Database and to expose a handful of new REST endpoints. Here’s what I still need: • Establish a clean, secure connection between the existing Flutter codebase and Firebase Realtime Database so reads, writes, and live updates flow without delay. • Extend the current FastAPI service with several small, well-documented endpoints (mostly CRUD) that the mobile app will call for user-specific data and app settings. • Make sure CORS, authentication hooks (already stubbed), and error handling remain intact after the new code is merged. • Submit a concise walk-through (README or screencast) so the rest of the team can reproduce the setup and run tests locally. Everything lives in Git; you’ll open a feature branch, commit frequently, and raise a pull request when the work is ready for review. I use Docker-compose for local spins and Postman for quick endpoint sanity checks—feel free to suggest improvements. When you reply, focus on your experience doing similar FastAPI/Flutter/Firebase work and how quickly you can turn around the integration. If you have a public repo or short demo that shows real-time database traffic flowing through Flutter, drop the link so I can take a look. Looking forward to tightening up this stack and shipping the next build together.
