Stefano joined OSI in 2021 after decades of open source advocacy, both as a contributor and leader. He co-founded and led the Italian chapter of Free Software Foundation Europe from 2001 to 2007, structured the developer community of the OpenStack Foundation and subsequently led open source marketing teams in several international companies. An enthusiastic open source user, he’s contributed documentation patches, translations and advocated for projects as diverse as GNU, QGIS, OpenStreetmap and WordPress. His appointment was a key step for the transformation of OSI into a professionally managed organization, a process that the Board of Directors started in 2020.
