A System Administrator keeps the lights on: servers, networks, identities, backups, and security. Everyone needs you, from small offices to product companies that just need things to work. This template helps you show your real impact with numbers instead of generic lines like 'maintained infrastructure'.
Copy these as starting points and swap in your own numbers.
2024–2025 estimates. Wide ranges by experience and seniority.
No, but you cannot get far without scripting. Solid Bash and PowerShell, plus enough Python for automation, are must-haves for mid and senior roles.
RHCSA and LPIC for Linux, MCSA or Azure Administrator for the Windows side, and CCNA if you want to lean into networking. International companies pay attention to these; local employers usually weight real experience higher.
Yes, it's the most natural path. Pick up Docker, Kubernetes, Terraform, and CI/CD, add a cloud provider (AWS or GCP), and within a year or two you can land a DevOps role with a meaningful salary jump.
Four to six for your most recent role, two to four for older ones. Fewer bullets with real numbers always beats a long list of generic duties.
Absolutely, especially if you're early in your career. Be specific: which hypervisor, how many VMs, what services you run. It shows genuine curiosity and hands-on skill.
