UI/UX improvement to an existing mobile app

I am looking for a UI/UX expert to improve the design and user experience of my existing mobile app, which is available on both iOS and Android platforms.

Specifically, I would like to enhance both the user interface design and user experience to make the app more visually appealing and user-friendly.

Ideal skills and experience for this job include:
- Proficiency in UI/UX design
- Strong knowledge of mobile app design principles
- Experience in designing for both iOS and Android platforms
- Ability to understand user needs and create intuitive and engaging interfaces
- Creativity in incorporating design elements and enhancing user experience.
