A resume summary is a 2-3 sentence statement at the top of your resume that positions you for the role. It's not an objective ("Seeking a challenging position..."). It's a pitch: who you are, what you bring, and why it matters.
The Formula
[Title/identity] with [X years] of experience in [core domain]. [Biggest achievement or specialization with a number]. [What you bring to the next role - optional].
The first two parts are non-negotiable. The third is optional, useful for career changers or when the target role differs from your current title.
5 Mistakes That Kill a Summary
- Writing an objective instead of a summary - "Seeking a position where I can leverage my skills" says nothing about your value
- Being generic - "Results-driven professional with a passion for excellence" could apply to anyone
- Listing soft skills without proof - "Excellent communicator and team player" is meaningless without context
- Making it too long - three sentences maximum
- Copying a template word-for-word - recruiters can spot them instantly

When to Skip the Summary
Skip it if:
- The role exactly matches your current title and domain (your experience speaks for itself)
- You need the space for more impactful content on a one-page resume
- You can't write anything more specific than "experienced professional in [field]"
A bad summary is worse than no summary. If you can't make it specific and quantified, leave it out.
Customize, Don't Copy
These examples are starting points. To make yours effective:
- Replace placeholder numbers with your actual metrics
- Match the job description's exact language
- Include your specific tech stack
- Tailor per application - a startup summary should emphasize different strengths than a Fortune 500 one
Once your summary is solid, the next step is making sure your bullets and keywords score well against the job description. WriteCV gives you per-bullet feedback with an honest ATS score.
