How to write your own Systems Administrator summary

  1. 1. Lead with a number. Years of experience or a headline result up front — recruiters skim the first line.
  2. 2. Name the outcome, not the task. Frame around keeping servers and services running, automating routine operations, supporting internal users, with a metric wherever you have one.
  3. 3. Mirror the job's keywords. Use the employer's exact terms (e.g. Linux, Windows Server) so the ATS matches you.
  4. 4. Keep it to 2–3 sentences. The summary is a hook, not a biography — the bullets carry the detail.
  5. 5. Re-tailor per application. Tailored resumes are associated with roughly 2.5x more interviews.
