Key Features:
- Upload Work Orders: Employees should be able to input and upload work orders directly onto the app.

Ideal Skills:
- Proficiency in Android app development.

- Strong skills in UI/UX to ensure the app is user-friendly for all employees.

The app should include distinct Admin and Employee roles for access control. The app should include basic integration capabilities with our existing systems. The app should include database synchronization with our existing systems to keep data consistent. No need for real-time notifications in the app. "The app should integrate with our existing systems, specifically none." The app does not need to support offline functionality. The app should include a reporting and analytics feature to monitor and analyze job progress and other key metrics. Include a feature to track and display job completion rates. The app should follow a functional and minimalist design to ensure straightforward navigation and functionality. No need for an employee location tracking feature.
