🎓 LMS Pro — Scalable Learning Management System

LMS Pro is a production-grade, full-stack learning platform featuring high-performance video streaming, automated assessments, and robust Role-Based Access Control (RBAC). Built for scalability, it supports complex workflows for students, instructors, and administrators with clean separation of concerns.

🏗️ System Architecture

LMS Pro follows a Decoupled Micro-Monolith design so heavy jobs (video transcoding, certificate generation) run asynchronously and never degrade the core learning experience.

🗺️ High-Level Overview

Tip: This diagram uses Mermaid. GitHub renders Mermaid automatically in markdown.

🔑 RBAC Portals

The system is partitioned into three distinct management portals.

Role	Portal Access	Key Responsibilities
Student	Student Dashboard	Consume content, track progress, take quizzes, earn certificates
Professor	Instructor Studio	Create courses, upload media, grade assignments, monitor analytics
Admin	Global Admin Panel	User governance, content moderation, financial reports, system health

🌐 Platform Workflow

1) Discovery & Learning Loop (Student)

• Onboarding: Instant authentication via JWT
• Enrollment: Secure checkout via Stripe triggers automated course access
• Consumption: Adaptive bitrate video streaming via CDN for low-buffer playback
• Completion: Quiz Engine validates performance → triggers PDF Worker to generate a verified certificate

2) Teaching Loop (Professor)

• Content Ingest: Drag-and-drop course builder saves metadata to MongoDB
• Video Pipeline: Transcoding converts 4K uploads into mobile-friendly resolutions (stored on AWS S3)
• Insights: Heatmap analytics highlight video drop-off points and lesson engagement

---

🛠️ Technology Stack

• Frontend: React.js, Tailwind CSS, Lucide Icons
• Backend: Node.js (Express), JWT Auth, Socket.io (real-time updates)
• Databases: PostgreSQL (transactions), MongoDB (content), Redis (cache)
• Infrastructure: AWS S3 (storage), CloudFront (CDN), RabbitMQ (task queue)
