    I have been involved with Linux professionally for the last 12 years. I have worked on setting up Linux servers, including almost all network services DNS, DHCP, Web servers, MySQL Databases, iptables Firewalls, proxies ... You name it, I've done it. I've supported various multinational petroleum companies and communication giants. I am pretty sharp debugging and troubleshooting network issues. I've also worked for the past 5 years almost exclusively on cloud computing. Be it multinationals like Microsoft, Canonical, Sun Microsystems, Oracle and others, to governmental agencies and SMBs I regularly support various smaller businesses remotely, with yearly contracts. So I'm pretty used to working remotely and getting things done that way. My scripting skills enable me to automate almost all of the needed daily tasks. I absolutely love doing Cloud/Linux/Unix design, administration and support work. I will surely enjoy supporting you and your environment. My friends tell me, "the servers love you" :) I'm sure yours will too!  less
