    Fred R.

    Solutions Architect & Entrepreneur

    United States - Tests: 1

    I'm a geek! I love technology, especially open standards and open source. I'm very creative and experienced in many different areas of enterprise technology, mostly concerning the internet or service providers. During the day I work for an enterprise solutions provider who is partnered with many of the largest names in technology, and I help very large businesses and organizations meet their technology solution needs. All the rest of the time I spend quite a bit of time on new ideas like virtulization, SDN and NFV, as well as any other project I find interesting. I also have a small virtual company called Geexology based on my work in my home lab with projects like opennebula, kvm, zfs, glusterfs, openvswitch, among others. Geexology isn't building the networks of today. We're building the next-gen networks of tomorrow. We have a lot of virtual infrastructure products, from your traditional SSL Certificates, Domain Registration and Trust Services, to newer Cloud Interconnections, such as Mesh VPN, NFV and Inter-Vendor Cloud Networking, VPS Brokering, CDN Services, DNS Security and even IPv6 products or projects. Find out what we can do for you! You can also find me on the internet as "flrichar" and on irc, I hang out specifically in a bunch of open source project channels on freenode.net.
