$git clone devops-learning-kit

I got DevOps certified. Here's everything I used to prepare.

While studying for the DevOps Professional Certificate by PagerDuty & LinkedIn, I put together a full study kit — notes, an exam simulator, and an interview guide. It's open source under MIT, so anyone preparing for the same certificate (or just learning DevOps) can use it, fork it, and contribute back.

Course Notes

Complete notes from all three courses — DevOps Foundations, Infrastructure as Code, and CI/CD — restructured into a logical flow, with hand-built diagrams in place of the original screenshots.

Exam Prep

An interactive simulator — 100+ questions, three difficulty modes, a live countdown, and scoring against the real 70% pass bar, with an explanation for every answer.

Interview Guide

40 real interview questions across Kubernetes, CI/CD, Terraform, deployments, security, and observability — model answers, what interviewers listen for, and diagrams for the flows you'll be asked to whiteboard.

Mock Interview

Practice out loud: the browser reads each question aloud and transcribes your spoken answer, then scores it against the key concepts. Chrome/Edge, mic required.
