EdTech Learning Platform
A course delivery platform engineered to handle thousands of concurrent learners without breaking a sweat.
The Overview
This client's previous course platform, built on an off-the-shelf LMS, kept slowing to a crawl during live cohort launches when thousands of learners logged in within the same hour. They needed a platform that could be trusted with their next launch.
The Challenge
The existing platform vendor offered no meaningful way to diagnose or fix the bottleneck, and the client had already lost learner trust after two rocky launches in a row.
Our Approach
We built a custom platform rather than patching the existing one, with load-testing built into the release process from day one rather than added at the end.
- Designed the video and content delivery layer around a CDN from the start
- Load-tested every release against simulated concurrent-login spikes
- Built a queueing system so login spikes degrade gracefully instead of crashing
- Migrated existing learner data and progress records with zero data loss
The Results
The platform has now run through several major cohort launches:
