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.

2024 managed a streak of 363 mapping days (unlikely to continue at that rate).

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).

If you have spare time try https://nominatim.org/qa/ , https://osm.mathmos.net/addresses/pc-errors.html , https://osm.janmichel.eu/taginfo/newkeys.htm
