React Native Developer for Health-Focused App

I'm seeking a proficient React Native developer to craft an engaging healthcare app for both iOS and Android.

The app features an interactive avatar, rewarding users for completing daily exercises. As users accumulate points, their avatar gains new skills, fostering motivation and engagement.

Key Screens:
- Splash
- Dashboard
- Display Abilities
- Daily Schedule
- Exercise
- Profile

Please note, the app is designed for two age groups: under 12 years and 12 years and above, necessitating minor adjustments for each group.

Important Features:
- The Dashboard screen should provide an overview of completed exercises.
- Progress tracking will be on a weekly basis.
- The Profile screen should include settings and preferences.

Skills & Experience:
- Extensive experience with React Native.
- Previous work on healthcare apps is a must.
- Strong understanding of creating interactive, gamified experiences.
- Ability to design for multiple age groups.

Please provide samples of relevant healthcare applications you've developed using React Native.
