Yasrab Testing System (YTS)

Developed a comprehensive Learning Management System (LMS) specifically designed for competitive entry test preparation in Pakistan (MDCAT, ECAT, NUMS). The platform features a robust online testing engine, video lecture integration, and a student dashboard for tracking progress. I was responsible for the end-to-end development, including the database architecture, user authentication, and the secure exam environment.

Handling high-concurrency during peak mock exam hours.

Solution: Optimized database queries and implemented server-side caching to ensure low latency when thousands of students take tests simultaneously.

Challenge: Securely delivering proprietary video content and preventing unauthorized downloads.

Solution: Integrated secure video hosting and token-based access controls to protect intellectual property.
