Oliver Simmons here! I mostly map in East Yorkshire, more precisely the Willerby/Anlaby area, to the West of Hull.
I am active in the OSM World Discord server.
What I do in OSM
I have been mainly adding houses and fixing up old OSM data as no-one else maps near me. But recently I did alot of work on Hull Infirmary hospital.
