During my active career, I was a high school math and computer science teacher. Now I am retired and consider LibreOffice my hobby.
I have been involved in LibreOffice and its predecessors for more than 25 years. This includes user support, writing manuals and core development. Since 2013 I have been a member of the Technical Committee for the further development of the OpenDocument Format (ODF) standard.

Thorsten is a LibreOffice hacker and standards wonk. During his now 20 years of tenure in the project, he's spent most of his time hacking the code in areas ranging from build system, platform abstraction libraries, Impress and Writer.

Thorsten's a computer scientist by education, and a Free Software enthusiast by heart, a geek from early childhood - and someone who was lucky enough to turn a hobby into an occupation. After first working for Sun Microsystems on then-OpenOffice.org, he then went with a number of others founding The Document Foundation and the LibreOffice project.

These days, his day job includes substantial amounts of project management and customer interactions, which does not prevent him from still messing with LibreOffice code. He's recently spun up his own company allotropia to have even more fun with open source all day!
