I am developing web-, desktop- and enterprise applications based on Microsoft technologies since 2001. In the beginning I learned about the basics of Visual Basic, C and SQL Server. Since 2002 I prefer C#, VB.NET and SQL Server, but I am always interested in adopting new skills like LINQ or Reactive Extensions (Rx). In 2005 I decided to work as a freelancer. I am supporting companies of all kind of business in in the realization of software-projects in the role of an architect or a coach, who imparts deep knowledge and shares experiences with other developers. I recommend the Clean Code developer value system which helps me to create and deliver software-solutions with outstanding quality in time.
