Quick question: Past/Present Tense

For an ongoing internship in the resume, I understand that a summary of the internship should be in present tense (e.g. "Build models, conduct research, etc)

What about for selected project experience? Since I already finished this project and accomplished something, shouldn't it be in the past tense? (e.g. Created a statistical database with data from over 1000 industry sources)

Thanks.
