Docs

The docssheet docs are long-form guides that build the mental model for a topic — what it is, why it works the way it does, worked examples, common mistakes, and how it shows up in interviews and on the job. They span Test Automation (SDET), Site Reliability Engineering (SRE), and Software Development (SDE).

Categories​

  • SDET Skills — Test automation, quality engineering, and SDET practices (e.g. Playwright, SQL, the tooling landscape)
  • SRE Skills — Observability, incident response, cloud, and reliability practices (e.g. Kubernetes, AWS, Terraform, OpenTelemetry)
  • SDE Skills — Software development topics and patterns (e.g. Python, Git, Docker, Clean Architecture)

Browse the sidebar to explore each category, or jump to the matching cheat sheet when you just need the syntax.

Every guide sits under exactly one of three tracks — pick the track that matches what you're trying to learn, then use its sidebar to go deep. If you're not sure where a topic lives, it's probably closest to whichever track's example matches your situation.
