A strong resume should make it easy for a recruiter to understand what you can do, what you have achieved and why you are relevant to the role.
Keep the structure simple
Use clear sections for your summary, experience, education, skills and relevant projects. Avoid unnecessary design elements that make the document difficult to scan.
Focus on achievements
Instead of only describing responsibilities, explain what changed because of your work. Whenever possible, include measurable outcomes, improvements or results.
Customize for the role
A resume should not be exactly the same for every application. Highlight the experience and skills that are most relevant to the position you are targeting.
Final thoughts
Your resume is not supposed to tell your entire life story. Its job is to clearly communicate your strongest evidence that you can add value in the role.
