I think, that my greatest achievement is introducing the systems of monitoring such as Zabbix, Cacti, Nagios at TSI. This systems are leading in the peace in this direction. I was build the systems practically from scratch with introducing new methods and functions , such as notifications to telegram by telegram-bot, importing data from Nagios to Zabbix and backward. In the future i must been realize second step of telegram-bot, which was can help users to fix them problems in automatical mode. Also I have expirience with with configuration a new cluster of servers with system of virtualization KVM Proxmox. It was a nice experience for me and good solution to improve the performance and resiliency of the company.
I think, that I'm interested be a part of one team and don't important it will be small team or big project. I'm ready to work anywhere, if this will be interesting for me in a future. For exemple , I don't sure, that I want work QA engeneer. I'm want and ready use my skills in a future works, so I search the work, which will be interest and match my experience, skills and my financial expectations.
