The Locked Office

You’re covering for an on-call engineer who’s off sick, there’s a live incident open — customers can’t view their account details — and the investigation was never finished. Everything you need is on the desk: an architecture diagram, the API docs, the logs, and a half-completed worksheet. Two locks stand between you and the open incident.

A free, bite-sized taster of SkillEmber. Learn to read a REST API, trace a failing request through an architecture, and review a system design — then finish the investigation to crack the codes. Everything that makes the full courses satisfying, in under half an hour.
