Gym Portal UI Development

I need a gym user interface portal that allows for user registration and login. The portal should accommodate three user roles: Regular Members, Trainers, and Administrators.

Essential Features:
- Regular Members should be able to:
- Renew membership
- View workout plans
- Track progress

Ideal Skills and Experience:
- Proficiency in UI/UX design
- Experience in developing role-based access systems
- Strong backend development skills to support user data and progress tracking

Looking for a developer who can create an intuitive, secure, and efficient portal. Please provide examples of similar work done.
