Class Management System Development

I'm in need of a full stack web developer who can create a comprehensive class management system. The primary focus of this system will be to track student attendance, marks, and facilitate online exams. It should cater to three user roles: Students, Teachers, and Administrators.

Key Features:
- A robust tracking system for attendance, marks and online exams
- Tailored user interfaces and functionalities for each role: Students, Teachers, and Administrators
- A secure, user-friendly Email and password authentication system

Ideal Skills:
- Expertise in full stack web development
- Previous experience in building user role-specific systems
- Strong understanding and experience with secure authentication systems
- Proficiency in creating intuitive, user-friendly interfaces

As this system will be accessible on both web and mobile platforms, I would appreciate it if you could include examples of similar projects you've worked on in your bid. I have a preference for the MEAN/MERN stack for development. Please note, the initial development should prioritize the user interface for Students.
