Scalable AI Education Platform
Architecting a production-grade EdTech platform for AI literacy courses at global scale
The Challenge
Video streaming infrastructure could not support simultaneous live and on-demand viewing at scale
Multi-user authentication with role separation (student, instructor, admin) was brittle and insecure
Mobile learners on low-bandwidth connections experienced frequent buffering and session drops
Course progress tracking and completion certificates lacked an audit trail for compliance
Content delivery latency varied significantly across Asia, Europe, and the Americas
Our Solution
Designed a multi-CDN video delivery architecture with adaptive bitrate streaming for all connection speeds
Built a secure multi-tenant auth system with JWT + refresh tokens and RBAC for three user tiers
Developed React Native mobile apps for iOS and Android with offline video download capability
Implemented a learning management system (LMS) core with progress tracking and certificate generation
Configured geographically distributed edge nodes for sub-100ms content delivery across target regions
Built an admin dashboard for course management, user analytics, and cohort performance reporting
