    Russia - Last active: 4 months ago - Tests: 5

    I have decided on career as an IT specialist long ago and today I have about twelve years of IT experience behind and a serious set of skills and knowledge, which I believe will help me to accomplish a good deal of the new interesting projects. My current experience in the IT field is quite diverse and it varies from Information Systems support and maintenance to enterprise servers and networks administration and this diversity in any case is a huge advantage, since there is no such task concerning computers, which I would not know how to start solving. I am looking forward to the new challenges, that will involve all my concentration, abilities and intellect and as result will become a considerable contribution into my employer stability and prosperity. In 2014 I obtained an assessment from Australian Computer Society inc. and the following employment after June 2010 is considered to equate to work at an appropriately skilled level and relevant to 262113 (Systems Administrator) of the ANZSCO Code.
