Websites: The following websites are helpful to develop a digital portfolio. Some may require subscriptions, but many have free versions available. Some of these websites help display samples of work for particular fields. For example, GitHub is a code hosting platform often used by computer science or engineering students. You can also ask individuals in your field what websites may be most commonly used.
LinkedIn: Note that your LinkedIn profile can be used as a portfolio if you are only planning to share work digitally. LinkedIn sections such as Experience, Education, Publications, Projects, and Honors & Awards allow you to embed hyperlinks to your work or even upload photos.
Google Drive/Direct Link: You can also share a link directly to a neat, organized file or folder with all of your work. Be sure if you share hyperlinks to samples of your work, that they are available to anyone with the link (especially if shared through Google Drive).
