Operational Bottlenecks & Technical Debt
The legacy Moodle portal suffered from frequent server crashes during mock entrance exams, poor mobile responsiveness, and high video piracy through unauthorized screen recording.
- ✕ Exam portal crashed when 15,000 students submitted tests simultaneously.
- ✕ Students in rural areas struggled with video streaming on slow 3G/4G connections.
- ✕ Lack of offline video caching led to heavy drop-off among mobile learners.
