The Story
Solving a real problem
with a useful product.
- Orbit closes race conditions that can let multiple buyers reserve the same limited-stock item.
- Its reservation engine uses Redis and Lua scripts to enforce idempotency, then asynchronously persists confirmed bookings to MongoDB.
- The system was load-tested with 5,000 concurrent buyers, holding 8,000+ requests per second at p99 under 604ms.
- A 223-test integration suite covers the purchase flow and its persistence boundaries..
