I have been working with LaTeX since more than a decade, with focus on the the automation of the typesetting process. Besides LaTeX I am a huge fan of Python and work a lot with pandas.
Some of my German & English articles can be found here: http://uweziegenhagen.de/?page_id=159
I am member and board member of Dante e.V. (http://www.dante.de), the German-speaking TeX/LaTeX users group and contribute regularly to Dante's magazine, the "Die TeXnische Komödie".
