My name is Jochen Topf. I am a professional software developer, author and Open Source enthusiast.
I work as a freelancer. In a former life that work was mostly about Internet services, especially email servers and anti-spam measures. Today it is mostly about geographic information services and spatial data, particularly related to OpenStreetMap.
Over the years I have written a lot of software, sometimes for clients and sometimes just for fun. Where possible I have released it as Open Source.
I like travelling to far away places.
