I'm a Senior Key Expert Research Scientist with Siemens . For the last 19+ 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 .
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 .
Some thoughts and remarks I write in my blog.
