Grown up in Berlin which I left in 2001. From that point I was living in Hannover, Genova, Beijing, Copenhagen and Nanjing. In 2011 I finally settled in Beijing until now.
Over the last 13 years I'm mainly active as software developer for industrial automation projects (i.e. powder metal facilities, industrial coffee roasters and industrial radio systems). Over the last 7 years I was busy with designing a high reliable radio system for more than 20 metro systems world wide. Cities in which this radio system is now running are Beijing, New York, Copenhagen, Hong Kong, Chongqing, Xian, Guangzhou, Qingdao, Dongguan, Fuzhou, Foshan, Istanbul and London. In the field of CBTC Signaling Systems this Radio is the most sucessful one in existence.
There is a list of articles and books I have written on real paper. Next to this I'm writing on bits and bytes in a blog about mruby.
I'm involved in some open source projects. One of my all time favorite is the programming language Ruby. Since May 2012 I work privatly as a core committer on mruby [commits]. I designed and implemented the mruby package manager, the test system, the documentation generator and the mirb (interactive mruby shell).
From time to time I'm attending and speaking at Ruby specific events. In 2009 I talked in Tokyo (RubyKaigi 2009) about the german-speaking Ruby community
. In 2010 I gave in Tsukuba (RubyKaigi 2010) a talk about the organisation of the early EuRuKo's
. In the same year I also spoke in Matsue (Ruby World Conference 2010) about how I used Ruby for Metro Systems
. In 2012 I was again in Matsue (Ruby World Conference 2012) to talk about how I used Ruby for Software Defined Radio. In 2013 I presented my work on mruby
in Tokio (RubyKaigi 2013) and Beijing (RubyConf China 2013).
