UI/UX Design for Comprehensive Yoga App

I'm developing a multifaceted yoga app akin to Practo, with features including video calls and consultations with professionals such as naturopaths and dieticians. The app will cater to various user roles - primarily yoga instructors, naturopaths, and dieticians.

Key features:
- The app's design should facilitate yoga instructors managing and scheduling classes.
- Naturopaths will engage with users through video consultations, messaging for advice, and providing access to health articles.
- A seamless, intuitive interface for users to navigate their health and wellness journey.

Ideal skills and experience:
- Proficient in UI/UX design with a portfolio of similar health or fitness applications.
- Understanding of designing for diverse user roles.
- Experience with implementing video call functionality in app design.
- Prior work with professionals in health and wellness sector will be a plus.
