Ethrai – High-Scale Government E-Learning Platform

Ethrai is a government-backed digital training platform designed to deliver professional courses and certifications to millions of users across Saudi Arabia. The platform provides enrollment, interactive learning, profile management, progress tracking, and certification.

My role focused on building and enhancing both the Angular portal and the .NET backend, ensuring the platform could scale reliably under massive real-world usage. The system supported millions of concurrent requests, requiring performance tuning, database optimization, and fault-tolerant architecture.
