my real name is Markus.
I`m an OSM member since 2008 and I started contributing to OSM in 2009.
Since 2013 I´m an OSMF member.
My main OSM mapping activities are address nodes and house numbers, mainly in Berlin.
In addition I´m sometimes adding some roads from Bing maps, a task which is quite relaxing after a long working day.
And last but not least I try to add all information of all receipts I get (restaurants, hotels, fuel receipts etc.) to the OSM database.
Here you can find out more about my activities.
My job is to run ENAiKOON, a telematics solutions provider and ginstr, a company providing a framwork for quick implementation of Android apps including backend support, both based in Berlin, Germany.
There is also an OSM wiki page about ENAiKOON.
ENAiKOON is using OSM features quite intensive: in total ENAiKOON runs 10 root servers with the following OSM services: tile servers, OSRM, Nominatim, Vector map data.
For giving something back to the community ENAiKOON has implemented various software for OSM, some of it without any commercial background.
Here you can find the ENAiKOON OSM acivities.
Currently the most prominent non commericial ENAiKOON project is Keypad-Mapper 3.
