Iván Valdés Castillo

I'm a back-end developer, currently working at Freshout. Mostly focused in backend web/API development, my main languages are Ruby and Objective C. But sometimes do some front-end JavaScript, XHTML, and CSS stuff. Talking about Ruby, I mainly use it with Ruby on Rails, Sinatra, DataMapper, and Rack. With Objective C, and Cocoa Touch do iPhone apps, that connect to API's done in Ruby, and sometimes native Mac applications.
