Having worked for over 15 years in both service provider and enterprise networks, I have built and managed 3 data center networks for hosting in large facilities. I have also built 3 metropolitan area networks as well as implementing a long-distance dense wavelength division multiplex network to connect them, scalable to 800Gbps. Implemented scalable and redundant multi-layer networks utilizing BGP, OSPF, policy-based routing and more.
While not my primary skill, I have over 15 years also administering Linux systems of various distributions. Currently, my primary experience has been with Ubuntu, server and desktop, as well as CentOS.
