Principle: every bullet needs an outcome
A strong resume bullet follows the action → object → outcome formula. What did you do, to what, and what changed because of it? If the third element is missing, the bullet reads as a job description and adds no signal.

How to use these examples
- Pick the bullets closest to your situation and rewrite with your numbers. Estimate conservatively when exact data isn't available — "~" and "approximately" are fair game.
- If you don't have a metric, name the scope: team size, product area, codebase size, user base, budget.
- Keep bullets to one line where possible — recruiters skim. A second line is fine for senior roles with complex scope.
