Motion and UI/UX Designer for App Prototype

I'm looking for a talented motion designer and app UI/UX designer to help me create a visually appealing prototype for my app idea.

Key Requirements:
- Design a prototype that is primarily focused on visual appeal.
- Incorporate complex gestures into the prototype, as opposed to simple click-throughs or just animated transitions.

Ideal Skills and Experience:
- Proficient in motion design and app UI/UX design, with a strong portfolio demonstrating both.
- Experience creating prototypes that are visually appealing and incorporate complex gestures.
- Ability to balance visual creativity with functional design.

Please provide examples of previous work that align with these requirements.
