  • Firebase Authentication and Firestore
  • Supabase authentication and database
  • REST API integration using JSON
  • GET, POST, PUT, and DELETE requests
  • User login, registration, and profiles
  • Connecting app screens to backend data
  • Push notifications
  • API error handling and debugging

WHY WORK WITH ME?

  • Clean, maintainable Flutter and Dart code
  • Solutions tailored to your requirements
  • Clear communication and reliable delivery
  • Agreed scope before development begins

HOW TO GET STARTED

Please message me with:

  1. A brief description of your app
  2. The service you need integrated

  4. API documentation or error screenshots, if available

I'll review your requirements and recommend a suitable package or custom offer.
