Professional
I'm a Senior Key Expert Research Scientist with Siemens. For the last 22+ years I have worked in the areas of communication, automation and manufacturing as an engineer, project manager and researcher. In these areas I hold several patents.
Private
My hometown is Berlin. Yet since 2007 I spend most of my time in Beijing. I'm active in the Open Source community in general with a special focus on Ruby. I'm a contributor to several OSS projects, a public speaker and an author.

Articles and Books
In the past I was asked several times to write technical information (mainly about Ruby) on real paper. The results were published in magazines and books. I'm not actively looking for author projects. Nevertheless, if you have a project in mind of which you think it fits my expertise, get in contact with me.
"Ruby - Das Einsteigerseminar"
In 2007 I wrote the german book "Ruby - Das Einsteigerseminar" (ISBN: 978-3826674594). This is a starter book for the Ruby programming language (version 1.8). It contained next to the introduction of the language itself an exercise area for each chapter and a project (photo management software) written from scratch in Ruby.
"Ruby die 1.9te"
Together with Florian Gilcher, I wrote in March 2009 the cover article "Ruby die 1.9te" for the german Ruby Magazin RailsWay. We covered the syntax changes since version 1.8, the regular expression machine called Oniguruma and introduced the new encoding system in detail.
"Wie das i vor den Ruby gelangt"
In May 2009 we (Markus Prinz and me) wrote the article "Wie das i vor den Rubin gelangt". This was also the cover article of the german Ruby Magazin RailsWay and covered the Ruby integration of MacRuby inside of Mac OS X. We illustrated the usage of MacRuby by programming a demo application to learn kanji on the Mac.
"Ruby Konferenzen"
After my trip to Japan in July and September of 2009 I wrote two articles for the german Ruby magazin RailsWay about the RubyKaigi and RubyWorldConference.
