Most resume action verb lists are useless. They're 300-word SEO dumps that conflate 'led' and 'spearheaded' and 'championed' as if those all mean the same thing to a recruiter. They don't. The right verb depends on what kind of outcome the bullet is describing. This guide is short on purpose.
The rule: pick the verb AFTER you know the outcome
Start with what actually happened. Then pick a verb that matches the scale, the kind of action, and the evidence. 'Led' with no team size is invisible. 'Rewrote' with no before/after metric is invisible. The verb is the second-most important word in the bullet; the metric is the first.

Pair every verb with a number
'Reduced deployment time' is half a bullet. 'Reduced deployment time from 45 minutes to 6 by moving CI to self-hosted runners' is a complete bullet. If you can't put a number on it, the verb is doing too much work.
The no-repeats rule
Across a one-page resume, avoid using the same verb twice. Three 'Led' bullets in a row reads as lazy. Skim your resume and flag any verb that appears more than once — that's the first pass of editing.
