Mobile App UI/UX Designer Needed

I'm seeking a talented UI/UX designer to create high-level mockups for a mobile application aimed at NGO volunteers. The app's primary function will be data collection, and the initial mockups should incorporate the following key features:

- User registration/login
- Data entry forms
- Dashboard overview

The application will be exclusively for the Android platform at this stage. If the initial task is completed successfully, we will proceed to create more detailed mockups together. Ideal candidates will have extensive experience in UI/UX design, particularly for Android applications, and a keen understanding of creating user-friendly interfaces for the NGO sector.
