Secure Doctor-Patient Scheduling Platform

I'm seeking an experienced team to develop a secure Doctor-Appointment System. This web application will need to incorporate authentication and authorization, as well as a RESTful API for improved access control and efficiency.

Key Requirements:
- UI/UX Design: Must ensure responsive design for mobile, fast load times, and intuitive navigation.
- Authentication Features: Two-factor authentication and social media login.
- Access Control: Role-based access control (RBAC) is needed.

Ideal Skills and Experience:
- Proficiency in building secure web applications with robust authentication systems.
- Strong background in UI/UX design for mobile responsiveness and fast load times.
- Experience with RESTful APIs and implementing RBAC.
