I am on gis.stackexchange.com to share my experiments with PyQGIS.
Not a cartographer or geodatawrangler at all my usecases are twofold:
- make one 'nice' map of cycle tours
- make maps for my mobile app http://slm.prdv.de
All code of this app is on GitHub at https://github.com/cprior/sunlightmap and my PyQGIS unittests (the first unittests I ever wrote) are in application/physical/GIS/qgis3-tests
