Patrick van der Velde. Online mostly written as Petrik.
Commercial software developer since 2008. Worked on projects in C#, Delphi and C++. Miles more skilled in C# than the other languages. As a bonus has a pet hate for C++.
Some things since birth, other things since a varying point in time since birth.
In general, and depending on the context, because I can, or because it's there. Pick one.
