Multi-Platform UI/UX Designer Required

I am seeking a talented UI/UX designer to create engaging designs for my Web, iOS, and Android applications. It's for a sports app which has several key design requirements:

- Onboarding in a way that makes it super easy, friendly, and engaging (e.g. simple sign up form process, dashboard notifications, quick product tour,....)
- Dashboard: We have loads of information and modules, but how do you display them in order of priority, hide some behind drop downdowns or swipes,...?
- Calendar and Workouts - There are so many details in these sections, it's important to display it well
- Account section has loads of options - consolidate, edit, delete,... everything must be questioned and thought through.

Overall, the design is good/okay, but it has to be expert level perfect and competitive in the sport.

IMPORTANT - Only expert level designer please apply. You must possess high abilities in UI/UX, app/mobile design, web design, wireframes, user journey, etc.

Ideal Skills:
- Proficient in UI/UX design principles
- Experience designing for web and mobile platforms (iOS & Android)
- Strong understanding of creating user-friendly onboarding processes

Please provide examples of your previous work in your bid.
