I work at Humanitarian OpenStreetMap Team (HOT). This involves training organizations how to create and manage projects on HOT’s Tasking Manager.

I first started editing OpenStreetMap in 2015 by taking part in Missing Maps university events in Scotland. I moved to London later that year and have helped coordinate the Missing Maps London events since.

In 2018 I completed a Masters in Geospatial Analysis at University College London.
