I am an expert at supporting the operation systems based on linux and its variants. Over the last 10 years I have worked with different kinds of technologies and software. During this period I have been involved in a large number of tasks related to servicing of simple and complex systems. My primary goals included uptime/ performance monitoring and security. I was a leader of the team consisting of fifteen specialists for four years. I was engaged in challenges of data backup, troubleshooting and user support. I've accumulated five-year experience at developing different software using Ruby, Python, Bash, HTML at system and user levels. This is a continuously expanding shortlist of software and technologies I deal with.
