The public-facing site and the entire admin dashboard are already coded; what I still need is the engine that makes the learning platform truly work. Here is the scope I want you to tackle: • Course management – The admin panel already has screens for adding courses, modules, recorded video lessons, PDFs and attached quizzes. Your job is to wire those screens to a database and build the APIs so an administrator can create, edit, publish, unpublish and delete content without touching code. • Quiz & mock-test system – The quiz UI is done and mimics today’s CBT exams. I need the backend logic (question pool, timer, auto-scoring, negative marking flag, review screen) plus a concise test-report page for students once they submit. • Student experience – Students must be able to enrol, resume where they left off, stream the videos through the third-party player I’ve embedded, download PDFs (where allowed) and launch quizzes tied to each lesson. • Roles – Only two roles exist: Administrators (full control through the dashboard) and Students (course consumption). No instructor role is required. Need developer who has prior experience of working on LMS before
