Developed and delivered an end-to-end scheduling service capable of handling diverse scheduling needs, including classes and tests, catering to over a million users.• Optimized Redis caching by reducing CPU utilization from 80% to around 20% through mitigation of thundering herd issues and hash slot contention; identified a bottleneck caused by clustering keys into a single Redis hash slot and resolved it by redistributing keys and applying TTL jitter to stagger expirations.• Implemented a course completion feature using RuleEngine; enabled users to input course details and a grace period, automatically marking courses as complete. This automation processes over 100k completions monthly.• Streamlined and optimized the process for ordering content displayed to students, successfully reducing the average processing time from 750 minutes to under 30 minutes using worflows, resulting in faster content delivery.
