    Russia - Last active: 6 months ago - Tests: 4

    10+ years of experience in enterprise software development for the last Russian telecommunication companies and Russian goverment. For the last years I've worked for Rostelecom (http://rt.ru) and a lot of other telecommunication companies in Russia. I was the instructor for the Oracle Administration Workshop course, and was the lead developer and the software architect for the one of the most secret organization in Russia: Prosecutor General's Office http://genproc.gov.ru/ (http://crimestat.ru - the public part of our work) and Russian Home Office. Our customers were very demanding, didn't know just simple things in IT, but we found the right way to help them. I like 'Unix way', but in our last projects we have used all the .NET and Microsoft server technologies. If you want to get expertise in enterprise software development, and get the right way to solve problems, I'll help you.
