Overview
What it does
Enterprise LMS & assessment platform with SSR, RBAC, and isolated code evaluation for live exams.
The Problem
Why it needed building
Live coding exams need to survive tens of thousands of concurrent submissions without leaking one candidate's code environment into another's, or crashing during finals week.
The Approach
How it was engineered
Built on TanStack Start for server-side rendering, with Supabase and PostgreSQL row-level security enforcing per-tenant RBAC, and isolated evaluation sandboxes handling code submissions on Cloudflare Workers.
The Outcome
Where it landed
Examly now handles 25,000+ concurrent exam sessions with code submissions scoring in under 1.2 seconds and zero downtime at peak load.
