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.

Architecture • RBAC • Workflow • Tech Stack • Structure • Getting Started • Roadmap

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

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

The system is partitioned into three distinct management portals.

• 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

• 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

• 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)
