I will build firebase or supabase backend and api integrations for flutter apps

I will build or fix a secure Firebase or Supabase backend and connect it to your Flutter app. I can set up authentication, database schemas, security rules, storage, real-time data, Cloud Functions or Edge Functions, REST APIs, webhooks, and third-party integrations. Send your current codebase, backend project, API documentation, or Figma flow. I will map the data model, implement the integration, test the main flows, and provide clear setup notes. Standard and Premium packages can include more tables, roles, storage, notifications, payments, and deployment guidance. Message me before ordering so I can confirm scope.
