Multi-Role Package Delivery App with gps and verification

I'm seeking a skilled developer to create an Android and iOS application for a comprehensive package delivery service. The app should facilitate interaction between multiple roles - senders, receivers, drivers, and parking points.

Key Features:
- Real-time GPS tracking: This is crucial for the tracking of packages throughout the delivery process.
- Proof of Delivery: The app should incorporate a feature that verifies package delivery to the intended recipient.
- Delivery Status Notifications: Users should receive timely updates on the status of their packages.

Ideal Skills:
- Proficiency in Android and iOS app development.
- Experience with GPS technology integration.
- Prior work on package delivery or logistics apps will be highly regarded.

All user roles and touchpoints need verification within the app, ensuring a secure and trustworthy service. If you have the necessary skills and experience, I'd love to hear from you.
