I currently have one web portfolio that is almost done and a python slot machine game I made.
Internships are funky because they’re almost always reserved for current students. Because of this, they’re pretty used to seeing most “projects” being school projects and learning exercises.
Generally speaking include links to a project only if you are genuinely proud of it and think it shows your best quality of work. List projects on a resume if you can say something interesting/important about them.
