Student Management and Virtual Classroom Platform

I'm in need of a comprehensive platform that caters to the needs of my students and faculty members. The platform should be accessible on multiple devices - both as an app and a web application, and should feature:

- **Grade Checking:** A system where students can effortlessly check and monitor their grades.
- **Schedule Viewing:** An easy-to-use interface that displays their schedules.
- **Absence Tracking:** A feature that allows students to keep track of their absences.
- **Library Access:** A digital library that houses course materials from each professor. This library should also have:
- **Search Functionality:** Students should be able to search for specific materials within the library.
- **Download and Save Capabilities:** Materials should be downloadable and savable for future reference.
-** news from the university like events

In addition, the platform should support virtual meetings similar to Zoom. However, it should have an enforced camera feature to ensure that students are engaged during these sessions.
Each student will have a unique login and password. Only I will have full administrative access. The platform should include electronic signatures for students to sign the university's policies. Access should be limited by role: an administrative staff member will manage attendance, professors will add course materials and input exam grades, and no one but me will have full administrative control. Professors and students will be users with different levels of access.

Ideal Skills:
- Proficiency in app and web development.
- Experience in virtual meeting platforms.
- Understanding of educational systems and student management.

This is a project that requires a good level of user experience design and development. Please provide a showcase of relevant projects you've worked on.
