Donald Hessing is Lead Microsoft Architect for Capgemini Netherlands and Programme Chair for ESPC17, ESPC18, ESPC19 and ESPC2020. With a strong developer background in ASP.NET and SQL Server, he changed his career in 2007 from .NET / SOA to SharePoint. Back in 2009 he became one of the first Certified Masters for SharePoint (MCM) in the world and is now, in his daily job, an architect. He is passionate about Azure and Office 365, but likes to solve real world problems, instead of always using the hammer. He likes to share his knowledge and findings in the community and has been frequently asked to speak or instruct at conferences including SharePoint Connections, European SharePoint Conference, Microsoft SharePoint Conference, SharePoint Saturday, CollabSummit and Microsoft TechDays.
