Cross-Platform Flutter Attendance App -- 2

I'm looking for a skilled developer to create a cross-platform Flutter-based attendance app for both Android and iOS. The app should encompass the following primary features:

- QR Code Scanning: Users should be able to check in by scanning a QR code.
- GPS-Based Check-In: The app should incorporate a GPS feature that allows for location-based attendance.
- Manual Entry: In instances where the above methods are not feasible, users should have the option for manual check-in.
- Face Embedding: The app should also incorporate a face embedding feature for attendance verification.

The app will need to integrate with a third-party API for its backend services. Therefore, experience with API integration is essential.

Ideal Skills:
- Proficient in Flutter
- Extensive knowledge of cross-platform app development
- Prior experience in creating attendance apps or similar
- Strong understanding of QR code scanning implementation
- GPS integration expertise
- Familiarity with face embedding technology
- Proven track record in third-party API integration
