Realistic App Design for iOS/Android

I am interested in hiring a proficient app designer with strong expertise in prototype design, wireframe design, and figma design. What's unique about this project is that it should be realized on both iOS and Android platforms. Realistic design is the preferred style that should reflect throughout the application. While I am open to color scheme suggestions, the design should be compelling enough to engage the users.

Skills and Experience:
- Thorough understanding of figma design, prototype design and wireframe design
- Proven experience in designing applications for both iOS and Android
- High creativity in implementing realistic design elements
- Ability to work with vibrant, light and/or dark color schemes
