I have joined OSM four years ago (in 2014) and have done 1671 changesets until today (March 11, 2018) You can get an idea about my acitivities if you take a look at Neis One Statistics and Neis One Heatmap
I have mapped intensively in the following parts of Africa and plan to keep on doing so:
Ethiopia, Amhara, Misraq Gojjam (East Gojjam) Ethiopia, Oromia, West Guji DR Congo, Tanganyika Province Tanzania
I have tried to contribute a bit to the great. meritous work of "HOT" (Humanitarian OpenStreetMap Team" and "Missing Maps" and had mapped 240 tasks yet (112 validated).
My recent contributions to the New Guinea Earthquake task brought me in contact with remote mapping in Papua New Guinea.
