Systems Administrator · Windows Server, VMware & M365 · 600 users

Linux Systems Administrator · RHCSA · Automation with Bash and Ansible

The pattern: role, registration, sector or speciality, one proof point. Keep it under 220 characters so it shows in full on mobile.

How to use these keywords

Name the platforms and their scale: servers, VMs, users.
Automation is a differentiator. Say what you scripted and the time it saved.
Backup and DR results (restore tested, RTO met) are strong evidence.
Mirror the advert. If it says "ITIL 4", write "ITIL 4", not a shortened version. Applicant tracking systems match words, not meaning.
Only use keywords your experience backs up. An interviewer will ask about every one of them.
