Nibras LMS

Project Description

🎯 Goals

Enterprise-Grade Educational Delivery: Build a high-performance, scalable learning management system tailored for high-school students and educators in Egypt and the MENA region.

Rigorous Content & Anti-Piracy Protection: Combat video theft, screen recording, and unauthorized distribution through tokenized DRM streaming (Bunny.net Stream) and strict single-device session enforcement.

Localized Financial Accessibility: Democratize online course enrollment by eliminating payment barriers for unbanked students through printable prepaid recharge scratch cards, local mobile e-wallets (Vodafone Cash, InstaPay), and physical center access codes, alongside international gateways (Stripe).

Multi-Modal Testing & Evaluation: Deliver an adaptable assessment engine supporting interactive auto-graded quizzes, PDF-based assignment submissions with teacher grading, and external exam integrations with completion tracking.

Gamification & Student Retention: Boost student engagement through an XP leveling system, competitive Top 100 Leaderboards, real-time notifications, interactive student-teacher live chat, and a modern, high-aesthetic Arabic UI.

👨‍💻 My Role & Responsibilities

Full-Stack System Architecture: Designed and implemented the complete software architecture from database schema design to responsive frontend interfaces using Next.js 15 (React 19), TypeScript, Prisma ORM, and PostgreSQL.

Security & Authentication Engineering: Developed a resilient dual-auth system (supporting Clerk Auth, Supabase Auth, and local session fallbacks with automatic foreign-key data migration), implemented concurrent single-device session invalidation (ActiveSession), and integrated an Anti-VPN/Proxy security shield.

Protected Video Streaming Pipeline: Integrated Bunny.net Stream API with dynamic signed token authorization, customized video player UI, and automated video completion percentage tracking.

Financial & Wallet Infrastructure: Engineered an internal student digital wallet system, batch printable recharge card generation with cryptographic validation, mobile cash transaction verification flows, and administrative revenue analytics.

Interactive Learning & Exam Modules: Built dynamic exam interfaces (MCQ with instant score computation, PDF submission workflows, and external form tracking), drag-and-drop course curriculum builder, and real-time support chat with file attachments.

UI/UX & Performance Optimization: Designed a premium, RTL-first Arabic interface utilizing Tailwind CSS, Radix UI primitives, Framer Motion micro-animations, GSAP transitions, and Three.js 3D elements, achieving fast loading times and smooth 60fps animations.

🏆 Results & Achievements

Eliminated Credential & Account Sharing: Reduced concurrent credential sharing to zero through real-time single-session enforcement, protecting creator revenue and course exclusivity.

Robust Video Security: Prevented lecture video extraction and unauthorized playback via tokenized URLs, customized player controls, and proxy/VPN filtering.

High Local Payment Adoption: Successfully facilitated friction-free purchases for students without bank accounts, with high adoption of prepaid recharge cards and mobile wallet transfers.

Enhanced Student Engagement: Interactive auto-graded testing, XP gamification, and real-time leaderboard rankings delivered measurable improvements in student course completion rates and daily platform return visits.

Scalable, High-Performance Foundation: Optimized PostgreSQL relational indexing, Next.js server-side rendering, and React caching to handle high-traffic exam submission spikes with zero downtime.
