My name is Francesco Frassinelli (frafra). I am a long time Python developer and GNU/Linux sysadmin and I am the vicepresident of PoliMappers. I studied at Politecnico di Milano where I got a BSc in Computer Science Engineering and I am currently enrolled in Geoinformatics Engineering.

My personal website is and most of my free software project are available at


I have added data near Vallecrosia and Vignate, but most of the changes I made have been made outside Italy, using HOT. I am also a Mapillary contributor.

I also developed some tools, including Is OSM up-to-date?
