Hello, my name is Gennadiy, I'm a system administrator with 7+ years of experience.
I have experience in:
- administration of Linux servers;
- administration of Web-hosting (Apache, Nginx, MySQL, etc);
- administration of FTP-servers (Pure-FTPd, ProFTPd, IIS);
- administration of virtualization (VMware vCenter, ESXi), Hyper-V, Proxmox;
- administration of databases (MySQL / MariaDB, Microsoft SQL Server);
- administration of Linux mail servers (Postfix, Dovecot, MySQL, DKIM, Postgrey);
- administration of Monitoring solutions (Zabbix, Munin);
- administration of DNS, DHCP, routing, iptables;
- developing scripts with Python, bash;
During this project great improvements have been introduced into my server network and infrastructure. The system became more stable, secure, easier to maintain and monitor and I also learned a lot about system administration myself because all procedures and changes were well documented. I would definitely recommend this freelancer and plan to cooperate with him more in future.

[19 November, 2018] He helped me set up Gitlab system and better understand how version control works and how could it be applied in my company.
[09 December, 2018] Updates he applied and suggested on Redmine, Zabbix and Gitlab systems made my company's infrastructure much more secure and easier to monitor.
