GPS Tracking Device & App Development

I'm looking for a skilled and reliable engineer and mobile app developer to help create a compact GPS tracking solution—both the hardware and the companion mobile app.

Hardware Requirements:

• GPS device size must not exceed 4x4 cm.

• Device must include a rechargeable battery.

• Charging must be contactless (wireless charging required).

Mobile App Requirements:

• Cross-platform (Flutter or React Native preferred).

• Compatible with both Android and iOS.

Core Features:

• Real-time GPS tracking: Display the live location of the GPS device on an interactive map.

• Geo-fencing: Set predefined monitoring zones. The app should send alerts if the device leaves the designated area.

• Battery monitoring: Show battery level of each device and send alerts for low battery.

• Notifications & Alerts: Push or in-app notifications for geo-fence breaches and battery warnings.

• Device Management: Ability to add, remove, and manage multiple devices.

Additional Information:

• The GPS device should be able to transmit data via an API to the mobile application.

• Previous experience with GPS tracking systems or IoT-based solutions is highly desirable. Please share relevant examples.

Deliverables:

• Fully functional prototype of the GPS device with wireless charging capability.

• Mobile app (Android & iOS) with the features listed above.

• API integration for real-time data transmission.

• Optional: Admin panel or backend system for device/account management.

To Include in Your Proposal:

• Your recommended tech stack and development approach.

• Timeline and estimated cost.

• Portfolio/examples of similar projects.

• Any hardware sourcing or manufacturing experience (if applicable).
