All time worked in conditions of minimal budgets due to what I learned to plan infrastructure and create scale-out solutions from low-cost equipment. The reason for the change of the activity: the lack of prospects in connection with the stagnation of the company.

Configure and support park of servers (under FreeBSD), network, IPSec network in the central office and branches. The reason for the change of activity: fundamental changes in the work schedule.

Setting up client hardware, configuration managed switches working with servers. Subsequently, the consultation of other employees. Achievements: • Gained experience in building data networks, including I learned to weld optical fiber • acquire knowledge of the principles of network operation. • Acquired extensive experience in the diagnosis and solution of the "bottom" problems Often I had to work without assistance, that taught to look for information, subject to analysis and solve the task on their own. The reason for the change of activities: interest in solving more complex problems, the desire for self-development.
