    Dear potential employer, I will be glad to help you with all my skills. But please note, I have full-time job currently. So if you have time-critical task, I suggest you to consider another candidates who have enough time. 6+ years of experience with all types of day-to-day web hosting support, network and servers administration. From shared hosting servers with thousands of sites to dedicated servers and clusters. From fixing of small problems in web applications and to urgent maintenance and recovery of hacked servers. And much, much more... Although I was working as system administrator, one of my main hobbies is programming and I always tried to automate routine administration task and create helpful applications. Starting from July 2013 I'm working as software engineer. In my everyday work I'm using python and wide range of frameworks and technologies to create GUI automation, network and web applications. oDesk is a great opportunity to spend some free time with profit for me (because I like to use my knowledge) and for you (yep, because I like to use my knowledge)
