Multi-Platform Development

I need three platforms developed: a learning management system (LMS), a portfolio and appraisal platform, and an availability and activity booking app.

The LMS is the highest priority, and it must include:
- Student tracking and analytics
- Support for video lectures and interactive quizzes

Ideal skills and experience:
- Experience in developing robust LMS platforms
- Strong background in student analytics and tracking tools
- Proficiency in integrating video content and interactive quizzes
