Smart Pet Activity Tracker Collar

I'm looking to develop an adjustable collar device for pets that will track various activities and behaviors. The device should be able to monitor:

- Daily Activities: Walking, Running, Playing
- Sleep Patterns
- GPS Location
- Barking/Meowing: Intensity and Duration

The data collected should be sent to a live app available on both iOS and Android platforms. The app will display all live data and allow users to upload samples for analysis.

The ideal candidate should have experience in:
- Wearable technology development
- Mobile app development (iOS and Android)
- AI model integration
- GPS tracking systems

Please provide examples of similar projects you've completed.
