This is not only for developers...it is also for others..plus this is just a intermediary between your potential recruiter and your portfolio website...there is an option to add a link to your personal website in the app...

It's agnostic toward the how a person wants to hire you...maybe for a full time job...or a someone looking to just pair program or a freelance job...

Plus it is easier to update your profile than change links on your website...
