It's up to you but I feel completely fifty/fifty.
Designer
I create design for websites, web applications and mobile devices. I do it from scratch based on the requirements of a client. So basically I visualize your idea and make it look good and easy to use.
Developer
As a developer I do lots of things starting with cross-browser HTML and CSS, doing amazing tricks with JavaScript and hardcore coding the backend with PHP/MySQL. Whether you need a new solution or fix to existing one it would be done!
OK enough designer/developer. All the Interweb knows who you are right now. But what kind of guy are you? Boring nerd who had lots of good marks, but no glasses, huh. Earned Master Degree in Computer Science (damn man you sound really boring now). Enjoy designing, contemporary architecture, mountain biking, supercars, travelling, skateboarding, surfing. Well that sounds better I can bookmark you just in case I need a guy to go ride some hills.
