In addition to the professional and purely private activities I have some additional hobbies – if time allows it. In general this means that others can finde something here too. My activities is often associated with non-profit projects or communities.


Since some time I take care of the Web portal of the Comprehensive TeX Archive Network. In 2011 I replied to a request for help of the CTAN team. I have limited time and I am professionally active in the area of Web portals. Thus I offered to build a new portal and maintain it for a while. End of 2012 the portal has been relaunched and I maintain and extend it since then.


Die TeX­nische Ko­mö­die is the quaterly publication for the members of DANTE e.V. – the German-speaking TeX users group. I have been active in the editorial board for several years. I have published some articles there as well.
