Summary

Experience bullets
Use ‘shipped’ when you owned release outcomes.
Skills
Verbs in experience; skills list libraries.
Experience bullets
Accessibility verbs need audit or user-impact context.

Common mistakes

Pretty UI claims without metrics.

Accessibility verbs without WCAG context.
Repeated ‘developed’ every bullet.
