Challenges
Echoes Lost In Orbit Welcome to the first challenge in the OffOn Challenge series! Your mission: restore interstellar communication by fixing a broken GitOps setup.

This is a hands-on journey through AI Observability with OpenTelemetry, OpenLLMetry, and Jaeger. ⚖️ Lex Imperfecta The Roman Republic has built a sophisticated legal system to protect its citizens — but the laws were written in haste, and the exceptions were written too generously. Policies go unenforced, the wrong citizens are exempt, and something has slipped through the gates unnoticed. As a newly appointed Praetor, your mission is to restore order before chaos takes hold. Building CloudHaven Welcome to the second adventure in the OffOn Challenge series! Your mission: modernize CloudHaven’s infrastructure from manual provisioning to a self-service platform. This is a hands-on journey through infrastructure as code with OpenTofu and GitHub Actions. Dead Reckoning The Grand Fleet’s commission office is buried in complaints. Manifests are filed but nothing comes of them. Vessels that do sail arrive at port with the wrong cargo, and no one along the route can explain why. As the fleet’s engineer, your mission is to restore order from keel to quayside and find out what the records are hiding. The Accessibility Nightmare This adventure was designed by Homayoun Mohammadi, a frontend developer with 4+ years building production apps in Next.js, React, and TypeScript. He contributes to open-source projects at Microsoft, W3C, and GitHub, and authored two npm packages: a 12-language RTL text engine and a TypeScript SVG mapping toolkit.
