Here are some synonyms for “assisted” to use on your resume:
Unless you’re describing work you helped with outside of the usual scope of your responsibilities, it’s best to avoid the word “assisted” on your resume.
You want employers to see your professional accomplishments and what you’re capable of, so it’s important to find words that emphasize your direct actions.
