    I'm a Ruby on Rails developer, with a good experience in Python (Django/Tornado/Scrappy) and PHP (Typo3, Drupal, CodeIgniter) as well. Basically, I prefer Ruby and Python for back end development now. Besides, I was a front end LD in the past, in a team dealing with eDetailing solutions development for mobile devices (mostly for iPad) based on web technologies, specifically html5/css3. I've got a good experience in building javascript-based application and their optimization for mobile devices that way. We were using the raw javascript (no frameworks) to be flexible enough, but in the mean time I've got the Backbone, Knockout, SenchaTouch and jQuery experience. Here's my technologies/frameworks/libraries skills summary: Javascript: Ajax, WebSockets, SVG, RaphaelJS, Touch devices.
