Build me a learning management system web app where students can sign up, log in, browse courses, enroll in them, watch video lessons, and track their progress as they go. I want an admin area too, so admins can add and edit courses, manage users, upload course content and videos, and see who is enrolled.

Please make it feel like a real modern product, with a clean dashboard for both students and admins, clear navigation, and role based access so people only see what they should. Include payment flow for course enrollment if that fits the app, and make sure the whole thing is wired up end to end with a React frontend and Node, Express, MongoDB backend.

If you need to look up current docs for anything, go ahead and do that.
