I have over 6 years of professional C++ programming experience, and I've dabbled in Ruby a bit (I love it, I would really like to work on it - Matz is a genius). Plus, in my previous day job I used to migrate code from VB.NET to C#, and write interop classes in C++/CLI, so cross-language stuff is my thing :P
