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.
