I am a consultant/programmer working for my own company, currently mostly programming in C#, but with extensive experience in C++, SQL, C, Java, Basic, PHP and even 8086 Assembler (although I have forgotten most of that!).
I also maintain the "Available C++ Libraries" FAQ, listing over 400 libraries for use with C++ (see my web page).
