I'm a Senior Software Developer, I prefer do not define the specific language, I have already been developing using python, C++, PHP, Java, Objective-C, Action Script (R.I.P =P) lol , Javascript. Depsite of i'm a java and javascript specialist, I usually I dont have a favorite language. I believe that code language is just the middle for achieve the goals of a project and each kind of issue has more appropriate solution.
