VisualCV is a great site for creating an online resume/digital portfolio. While there are a bunch of services out there like this, none of them are any easier/better looking to use.
There are some perks to getting the paid version such as customizing your URL, creating a badge w/ a photo, etc. but the free version is more the enough to create a professional looking piece of work.
