Cofounder OpenCage. Software engineer. Geocoding. Cycling. Speaker at several SOTM conferences.
Managed to survey a whole city (10x10km) in a four month project by walking and cycling every street, paths and taking lots of photos.

Interested in timezones, elevation, ocean/sea, disputed border data and general tagging validation tools.
Recently cleaning up postcodes all over the world (those too long, too short, in the wrong area).
