Flutter App Development / Django

My Flutter app is currently partially completed, and I'm looking for an experienced developer to help me bring it to the finish line. It needs the following functionalities:
- User Authentication: The app must allow users to create accounts and log in securely.
- Payment Integration: It should also support payment processing to enable in-app transactions.

I'm looking for a developer who has a strong background in Flutter app development, particularly in implementing user authentication and payment gateways. Your attention to detail and ability to work efficiently will be highly valued. Please provide examples of your previous Flutter projects.
