I'm 35. OpenStreetMap got me busy for 15 years now, mainly about infrastructures and public utilities topics. It began as a hobby prior becoming a game changer in my professional background. I'm involved in mapping mainly in France and interested in tagging development as well. Crowdsourcing very important knowledge thrills me to tackle crucial challenges like energy transition or climate change resilience. Sustainability, open source, open data and common good are also additional motivations to collaborate withing this community.
