FlutterFlow Backend Development & Integration

I am building a FlutterFlow-based mobile app and need a developer who is comfortable working mainly on the server side. Your first task will be to design and provision a solid MySQL database, map out a clear schema and set up all tables, indexes, and relationships so the app can scale without performance issues.

Once the data layer is ready, I’ll rely on you to wire it to FlutterFlow through clean, well-documented APIs. The project involves three distinct integration paths:
• Third-party services that supply user-generated content
• A small set of internal REST endpoints we already use on the web version
• A payment gateway to handle one-time and recurring purchases

All endpoints must return JSON, follow REST conventions, and include basic rate limiting and error handling. I’ll share the current app flow, screen states, and sample payloads the moment we start, so you can stub everything quickly and then move to production-ready code.

Deliverables
• MySQL schema (SQL dump + ERD)
• Deployed MySQL instance (cloud of your choice)
• API source code with clear instructions to reproduce locally and on the chosen host
• Postman or cURL collection for testing every route
• Integration inside FlutterFlow with working data queries and mutations

Acceptance criteria
1. CRUD operations complete in under 300 ms round-trip for 95 % of requests on a basic VPS.
2. Payment gateway returns success/failure webhooks that reflect instantly in the app UI.
3. Code passes simple linting and unit tests I’ll provide.

If this sounds like your kind of challenge, let’s get started—I’m ready to move fast.
