Put the role you seek, relevant recent experience, and concrete outcomes where a reader can find them quickly. Use plain section headings, consistent dates, and concise bullets that explain what you did and what changed as a result.
Tailor terms to the job honestly; do not add skills you cannot discuss. Keep formatting readable in both screen and PDF views, and check the exported file for broken spacing or lost text. A resume builder can help structure the page, but it cannot choose your strongest evidence for you.
Remove personal details the application does not require.
