Resume Tips

Quantify everything: Instead of 'built APIs,' say 'built 20+ APIs serving 500K users/month.' Tailor for API developer salary negotiations.

Listing skills without context or proof from experience, making them look generic.

Using vague bullets like 'Worked on APIs' instead of quantified achievements.

Ignoring ATS by stuffing keywords unnaturally or using tables/images.

Omitting metrics; always say 'improved performance by X%' not 'improved performance.'

Failing to tailor for each job, missing keywords like 'API integration jobs' from the description.
