I love to write software. More then two decades ago I managed to make my hobby my full-time job so I spent more then 20 year writing professional software (I guess that makes me a "Senior Software Developer"). The last few years I spend most of the time developing in C#/.Net for all kind of windows-, web- and embedded-software.
