Tips for software and IT resumes

  • List languages, frameworks and tools in Skills, and name them again in the job or project where you used them.
  • Add links: GitHub, a live project or a portfolio.
  • Show scale and impact: users, response time, uptime, money or hours saved.
  • Before you apply, paste the job advert into Dossier4u's ATS check: it lists the skills, years and qualifications the advert asks for that your resume does not show yet.
