Martin Winter

Martin Winter has a Bachelor in Computer Science and started with his first Internet connection in 1991. After working for a few years in Switzerland, he moved to the United States in 1998 where he worked for some time as a Backbone Network Architect at Exodus Communications (a large Colo provider) before spending (too) many years at Cisco. Since late 2011, he has been dedicated to Open Source. 

Initially working on Quagga for ISC, he later co-founded the non-profit Network Device Education Foundation (NetDEF) and helped start the FRRouting project. At NetDEF, Martin is the main person testing infrastructure for the FRRouting community. Martin enjoys travelling and Open Source Software and has a hard time understanding why people are still using closed/proprietary software. He is fluent in Swiss German, German, and English but failed in French.
