Multi-Tenant LMS with Real-Time Collaboration
Built full-stack Learning Management System with multi-tenant architecture supporting educational institutions, businesses, and individual learners. Implemented comprehensive features including video learning platform with Cloudflare Stream, real-time chat with Socket.io, dynamic assessment system, Stripe payment integration, and internationalization supporting English, Arabic, and Spanish.
Educational institutions needed a scalable, feature-rich LMS that could handle diverse user types (admin, manager, student, business student), complex role-based permissions, subscription management, video content delivery, real-time communication, and multi-language support—all while maintaining performance, security, and data isolation across tenants.
Architected Next.js 14 application with App Router, Server-Side Rendering, and TypeScript for type-safe development across 25+ interconnected database models
Designed complex PostgreSQL schema with Prisma ORM supporting multi-tenant architecture, hierarchical content structure (Courses → Chapters → Modules → Videos/Quizzes), and user progress tracking
Integrated Cloudflare Stream for enterprise video delivery with custom progress tracking, automatic chapter completion, and playback controls with event handling
Built production-grade real-time chat system using Socket.io with live user presence tracking, message delivery with read receipts, emoji reactions, file attachments, and group chat for business teams
Implemented comprehensive Stripe payment processing with subscription management, automated billing, webhook handling, and price table integration with dynamic pricing across three tiers
Designing database schema and application logic to support multiple organizations with complete data isolation, role-based permissions, and business-specific course allocation while maintaining performance.
Implemented tenant-based data segregation at database level, created hierarchical permission system with middleware protection, and built dynamic routing based on user context. Ensured complete business isolation with category and course allocation mechanisms.
Building production-grade real-time messaging system with Socket.io supporting thousands of concurrent connections, message persistence, presence tracking, and file attachments.
Architected Socket.io server with connection pooling, heartbeat system for connection management, and custom stores for chat state and online users. Implemented message queuing, read receipts, reactions, and file upload with progress indicators. Achieved reliable message delivery with offline support.
Integrating Cloudflare Stream for video delivery with custom progress tracking logic, automatic chapter completion, and synchronization with database state across hierarchical content structure.
Built custom video player controls with Cloudflare Stream SDK, implemented sophisticated progress tracking algorithms calculating completion percentages at module, chapter, and course levels. Created event handling system for playback events with automatic state synchronization.
Implementing NextAuth.js with custom credentials provider supporting 4 user roles, session management, subscription-based access control, and middleware-protected routes.
Designed custom NextAuth configuration with role-based callbacks, built middleware for route protection based on user type and subscription status, and implemented session management with JWT tokens. Created subscription expiration handling with automatic access revocation.
Mastered distributed systems design patterns: service discovery, circuit breakers, saga pattern, event sourcing, and CQRS.
Deep expertise in database optimization, caching strategies, load balancing, and performance profiling at scale.
Led architecture review meetings, established RFC process for technical decisions, and mentored developers through complex technical challenges.
Established 'you build it, you run it' culture with comprehensive monitoring, on-call rotations, and blameless post-mortems.
