Charles started with open source in 1999 as a founding member of Vovida Networks, developing some of the industry’s first open source VoIP protocol stacks and applications. Now at Cisco, he is a recognized champion of open standards, open source, and interoperability. He runs DevNet’s Open Source Dev Center, which focuses on Cisco’s major open source contributions, use, and community engagements, including OpenStack, OpenDaylight, and OPNFV. Last year, he successfully introduced open source hackathons into IETF and MEF, revolutionizing the way these SDOs operate and uniting open source software with open standards to maximize the pace and relevance of both. Charles speaks regularly at CiscoLive and has also been a speaker at previous OpenStack, RedHat, LinuxCon, and MPLS SDN NFV World Congress events.
