When you apply for a job or internship, employers will want to see code you've written so that they know what you're capable of doing. Spend some time getting your GitHub profile looking good. Make sure every repository has a
README file that:
Go through all files in each repository and make sure that there aren't large sections of commented-out code, bad indentation, extra line breaks, or anything else that looks less than professional.
Pin a couple of your best projects to the "pinned repositories" section, so employers can more easily view the work you'd like them to see.
Don't delete too many of your repositories, as it will get rid of the commit history, and employers value being able to see the amount of work that you've done. Pinning repos helps to highlight some of your more finished projects.
Later on, also make sure to fork your internship project, so that you have a copy of it on your profile for employers to see.
