One line, before and after
Original: Administered 120 Linux servers. Wrote Ansible playbooks for patching that cut patch time from two days to three hours.Suggested: Cut patching for 120 Linux servers from two days to three hours with Ansible playbooks.
Why this changedThe time saved is the headline; the fleet size frames it. Every figure in the rewrite is in the original line; nothing is added.
Section order
- Summary
- Experience
- Certifications
- Skills
- Education
Where your resume has these sections. A section your resume does not have is not added.
Mistakes that cost interviews
- Duty lists with no environment size
- A wall of technologies with no context
- Team achievements written as personal ones
- Seniority words the resume does not support
Evidence that counts in software engineering
- Systems or features worked on, and the candidate's part in them
- Scale: users, requests, data volume, latency, cost
- Measured effect on reliability, performance or cost
- Stack named where it was used, not only in a skills list
- Code review, mentoring and design work for senior roles
- Shipped side projects or open source for early careers
Use what your resume already shows. A line without a number can still be strong when it says clearly what you did and where.
These are common reading conventions drawn from hiring guides and career services, not rules every employer follows.
