Dan Teodosiu’s Summary
Dan has 20 years of experience developing successful consumer and enterprise software and services.
As the Director of Global Product Development–Europe, Dan founded and built a global development hub for Microsoft in Ireland between August 2006 and October 2008. Dan hired a top-notch team of over 50 people and managed it through several successful release cycles. Project areas included mobile applications and infrastructure, edge computing and datacenter management, and advanced visualizations for web analytics.
Previously, Dan was an architect in Windows Live/MSN where he evangelized, secured top-level executive funding for, and led the s-drive initiative to deliver a set of highly innovative scenarios. These included Sharing Folders (part of Windows Live Messenger), one of the largest secure P2P file sharing networks.
Prior to MSN, Dan was an architect in the Windows Server division, where his team shipped the Distributed File System and File Replication Service in Windows Server 2003, and developed DFSR, a state of the art file replication service that is a key component of the branch office support in Windows Server 2003 R2, and also part of Windows Vista and Windows Server 2008.
Dan joined Microsoft in 2002 through the acquisition of XDegrees, a Bay Area start-up he co-founded to develop a P2P solution for secure file sharing. As the CTO of XDegrees, Dan recruited and managed a top-notch engineering team.
Prior to XDegrees, Dan co-founded and led the engineering for Xift, a search engine and automatic directory construction technology.
Before Xift, Dan defined and helped build the first version of the Virtual Partitions product while at Hewlett-Packard Labs. Some of Dan's prior industry experience includes working for Alcatel Research in Europe and developing Lisp compilers.
Dan holds a Ph.D. and MS from Stanford University. He has filed over 50 US and international patents.
