Everything you need to go from concept to production
Structured Content
Every topic runs through the same four-part spine: a concept flashcard, a scenario quiz that tests the trade-off, a hands-on course chapter, then an interview drill to lock it in.

Every topic holds its cards, course chapters and interview questions in one place — sequenced so each concept builds on the last.
- Concept flashcardThe mental model — stated plainly, no fluff.
- Scenario quizSame idea, tested against a trade-off you’d hit in prod.
- Hands-on course chapterTerraform and Helm, built chapter by chapter.
- Interview drillRapid-fire recall under time pressure.
Cheat Sheets
Copy-paste command references baked straight into the flashcard content — no separate tabs, no hunting through docs mid-incident.

kubectl rollout status deploy/api -n prod
kubectl rollout undo deploy/api -n prod
kubectl logs -f deploy/api -n prod --since=5m

Not just Kubernetes trivia. Networking, IAM, cost, observability, and the AI tooling now showing up in platform interviews.
