3 mistakes that are killing your dev resume
A dev resume is not a list. It is a context and impact sales doc.
After reviewing more than 25 developer resumes (mobile, backend, fullstack, career changers), the same 3 mistakes kept showing up.
1. talking tasks, not impact
Section titled “1. talking tasks, not impact”The most common error is a resume written entirely like this:
- “Development and maintenance of applications…”
- “Worked on bug fixes and new features…”
- “Responsible for system X…”
That says nothing about:
- the size of the problem,
- how hard the work was,
- the impact on the product or the business.
Recruiters read this all day. It turns into noise.
Fix: turn each bullet into technical action + what + how + metric or scale.
2. layout that kills ATS and readability
Section titled “2. layout that kills ATS and readability”Another classic: a beautiful resume full of columns, icons, colors, emojis, and creative UX, and completely indigestible for someone who needs to read fast (or for an ATS).
The usual offenders:
- multi-column layout, heavy sidebar, icons, emoji in dates, cluttered header
- inconsistent dates and sections (“Aug 24”, “08/2024”, “2024 - present”)
- important sections missing or weak: Projects, poorly separated Skills, giant blocks of text
Fix: one column only.
3. stack misaligned with experience (or too shallow)
Section titled “3. stack misaligned with experience (or too shallow)”I saw this a lot:
- a giant skills list (Java 8 years, Docker, Kubernetes, AWS, Flutter, React) that never appears once in the roles
- technologies listed only under “Skills” with zero proof in experience or projects
- missing basic dev keywords: Git, testing, CI/CD, REST API, cloud, even for people who clearly use them daily
- a career in infra, support, or teaching, but a resume saying “full-stack dev” without describing a real project or product
Fix: only list tech you can defend in an interview, and tie each one to a role or project.
