Hi. I'm Sascha Manns from Germany. Since 1986 im working with computers. Over the years i worked with a C64, i286, i386 and other computers. I real like to work with them. So i started programming with BASIC, then Visual Basic, Ruby, Python and now C#. I learned MySQL, MS-SQL and Intersystems Cachè. I worked with different APIs and technologies like SOAP and others.
Since a few years i'm working as Windows Insider.
Over the years i worked in the bank sector, the healthcare sector, and wrote cross-platform apps for customers. Also i worked inside the openSUSE Linux project and other open source projects. I wrote internal documentations and public books for different targets.
