I think you need to look at a more compelling font. Something catchy, more in tune with your business. The one you have now is too plain, too boring. I get the impression that your site is both about design and coding? Maybe try using two types of fonts? Though a bit cliche, a simple monospace font may work nicely for the "code" text. Maybe try throwing in some html characters? symbols? Think about font weights and kerning. All these play an integral role in a solid logo.
I understand you want to use the door icon in the logo, but dont get stuck on that. Keep your mind open to other ideas. With a strong font you may not even need an icon.
