Personal GPS Tracking Device Development

I am seeking an expert with significant experience in GPS technology and device development to implement a highly precise tracking system onto a personal device.

Key Features:

- Real-time location updates: The GPS system must provide live location data with precision. Your experience could range from app development to gadget programming.

- Movement history log: The tracker should be able to store and display past movement paths. An understanding of data visualization and storage would be beneficial for this.

- Boundary alerts: The system should alert the user if the tracked item leaves a predefined area. Skills in programming alerts based on location data are critical for this.

- Particular Use: I have planned to use this tracking system specifically for locating lost or stolen items. Any past experience or knowledge in developing tracking devices for similar assets would serve as an advantage.

Do note that a key aspect of the project involves balancing precision with battery life and device size. Professionals with a proven track record in achieving this balance will be preferred.
