It didn't take me long to figure out the purpose of the site but - then again, I shouldn't have to work it out / think. Check out Steve Krug's book on UI design, Don't Make Me Think. The title says it all.
Correct me if my assumptions are wrong but I sense some scaling issues just around the corner. The live search doesn't make any AJAX requests - will the app always start with every listing on the homepage? How will it behave when you have hundreds or thousands of listings?
The Technologies taxonomy is not what I would expect (no programming languages). Is MySpace really a technology you'd list on your resume? Perhaps I've not quite got who the site is aimed at. If that's the case then (as others have said) you should make that explicit, in bullet-list style on the homepage.
Link the logo to the homepage. Lose the icons. Bump up the font size. Add some visual hierarchy to the listings to make them easier to scan (the dev's name isn't the most important piece of information in the listing).
crickets Not sure what that is/means.
What's your strategy for filling out content?
