WG Chair Biographies

Marcos Sanz Grossón is responsible for software engineering at DE-CIX, helping to build the biggest Interconnection Platform worldwide. More than 20 years of working experience in the Internet industry are behind him; past professional stops include leading positions at the German top level domain registry, DENIC, and the Council of European National Top-Level Domain Registries, CENTR. He holds a master's degree in Telecommunication Engineering and he is active in different communities (RIPE, IETF) and is co-author of a number of RFCs.

Marcos believes in open source based on open specifications. During his chairman term at the ID4me Technical Competence group, he led in evangelising the idea (and the code) of a decentralised Single Sign-On system on top of domain names. Now he is supporting the IX-API initiative, an open standard to provision services at Internet Exchanges (IXs). You will still find some of his code in git. Although he is not that fluent in Java or Go anymore, he is still fluent in Spanish, German and English.

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.
