Auto-scaling LMS platform handling high-volume online exams and video delivery.
Online testing platform, Pune• Custom production development project.
Before & After Impact
A side-by-side comparison of key operational indicators measured during our initial audit vs. 90 days post-deployment.
What They Were Facing
A breakdown of major operational friction points prior to our team's integration and custom build.
An online school suffered from database load spikes and site crashes during exam schedules. We refactored their video and testing servers to run on auto-scaling serverless nodes and configured an edge CDN cache, ensuring site stability for 25,000+ simultaneous test takers.
- !Exams with 10,000+ simultaneous users caused database crashes.
- !High bandwidth bills from raw video hosting.
- !Slow mobile load times for users in tier-3 cities.
We had zero visibility on our daily logs, and errors were cropping up in invoicing sheets regularly. We had to fix it before expanding our footprint.
How We Solved It
We mapped database schemas, engineered APIs in modules, and launched pilot releases to assure stable rollouts.
Migrated web servers to auto-scaling serverless lambda configurations.
Configured optimized video compression formats and regional CDN caches.
Built a dashboard to track student exam score logs.

The Outcome
Measurable metrics logged post-release that directly resolved client operational overhead.
Handled peak concurrency of 25,000+ active test takers with zero downtime.
Reduced video delivery costs by 40% using CDN caching.
Optimized mobile load speeds to under 1.5 seconds.
“We went from frequent server crashes during exams to total stability. The transition to the serverless structure was completely unnoticeable to our students.”
