Case study
Engineering Walid Educational Platform with Database Isolation
How we architected a high-concurrency learning platform featuring complete tenant database isolation, anti-piracy video streaming, and automated exam grading.
Challenge
Delivering a multi-tenant education platform with complete database privacy per teacher, low-latency secured video playback, and zero-degradation performance during concurrent exam sessions.
Approach
Implemented an isolated database per tenant model, custom encrypted HLS streaming with dynamic student watermarking, and optimized in-memory query pipelines for high-volume assessments.
Outcome
A live, production-hardened platform reliably serving thousands of active learners daily with sub-200ms API response times and zero data leakage.
