I'm not a developer but a designer. What do developers showcase in their portfolio? How do you describe the projects you've worked on? What is a recruiter looking for when visiting your website?
A developers profile these days is mostly just github. Works very well for those of us that contribute back to open source but not too sure how someone who doesn't contribute to os stuff would show a portfolio...
A portfolio can also consist of project writeups/screenshots and/or links to live sites.
