I am an iOS developer who also enjoys working on the full stack. You can view some highlights of my iOS portfolio at https://prezi.com/nmyqiycbmyia/scott-carter-ios-portfolio/
On the front end I've worked with HTML, CSS, Javascript, jQuery, YUI, Twitter Boostrap, etc. On the back end I've used Ruby on Rails, PHP, Perl and C++.
My current favorite revision control system is Git, but I've also used SVN, Perforce and CVS.
I like getting my hands dirty on the server (Linux, Apache, scripting, etc.) and have experience using Amazon Web Services (EC2, RDS, SimpleDB).
I also enjoy sharing what I learn - check out some of my projects at https://github.com/scottcarter and my blog posts at http://finalize.com/
