Android Teacher Attendance App with Fingerprint Integration

I need an Android mobile app designed for teacher attendance and management. This app should have a fingerprint scanner integration for attendance tracking, and it should be capable of syncing data both online and offline with cloud backup on AWS (Amazon Web Services).

Features:
- Fingerprint scanning for teacher attendance
- Manual check-in and QR code scanning options for flexibility
- Robust cloud backup using AWS
- Offline functionality with seamless online syncing

Ideal Skills:
- Mobile app development, specifically for Android
- Experience with fingerprint scanner integration
- Knowledge of AWS for cloud backup
- Understanding of offline and online syncing

A developer with experience in creating similar apps will be preferred. Please provide examples of your previous work in your proposal.
