    Linux & Puppet Systems Administorator

    United States - Last active: 1 day ago - Tests: 9 - Portfolio: 1

    I have worked for many years in the managed services and server hosting industries, and have worn many hats. Everything from basic website management to troubleshooting large scale multihomed websites with clustered MySQL database backends. Currently I am handling Linux administrative and devops development work in both chef and puppet, in both Rackspace and AWS cloud provider spaces. What am I experienced with? The list is long: * Linux RHEL/CentOS, Gentoo, Debian/Ubuntu? You name it I've used it. * Configuration Management / devops I am currently and have previously supported customers with large deployments via chef and puppet. This is the kind of work I enjoy doing, so if you need someone who can handle a puppet manifest or chef cookbook I'm the guy to talk to. * Enterprise Networking. I have not only supported customers with their networking needs, but I maintain an extensive home lab for tinkering and testing. This includes a Cisco ASA 5505 and Catalyst 2960 switch. * Virtualization. Xen, VMWare, KVM, AWS, you name it I've worked with it. I'm currently looking to expand that experience a full fledged openstack deployment. * Storage. Whether it is something relatively mundane like NFS, or something complex like Ceph or your SAN/NAS' iSCSI or fiberchannel HBA. * Cloud hosting I am currently supporting clients in Amazon, Rackspace, and Digital Ocean. Further, I used to work for Rackspace so I have experience on both sides of the asile with their products. In summary I have been doing this long enough with enough different products and companies that I can meet any challenge put forth to me. With your assistance, my presonal github repository will gain something new and interesting. Personal blog: http://jowrjowr.github.io/
