Hello, my name is Andrii.
In my childhood, I spent a lot of time with a soldering iron, making different interesting things.
At high school, I got a PC at home and started... Dos, Win, Linux, FreeBSD.
At the present time, I have more than 20 years of Win experience and more than 16 years of *nix experience.
I like to build systems and solve interesting issues.
OS - FreeBSD, Linux (CentOS, Alma, Rocky, RHEL, Ubuntu, Debian, Gentoo, etc), Windows (3.1-2019)
Virtualization - vSphere 5.x, 6.x. Standalone ESXi and clusters with SAN storages (iSCSI). KVM, Proxmox, oVirt. Veeam BnR, XSI-backup. VmWare Workstation, VirtualBox.
Web servers - Apache, Nginx, Lighttpd, Tomcat
DB servers - MySQL, MariaDB, Postgresql, MongoDB
Mail - Postfix, Courier/Dovecot/Cyrus, Rspamd, Postgrey, Clamav, PostfixAdmin, SquirrelMail, Roundcube, Sendy, AWS SES.
I have experience with WHM/cPanel, Plesk, VestaCP, Virtualmin, ISPmanager, but I don't like control panels (most projects are optimized for best performance, and there is no place for CP). If needed, I can learn and work with any control panel.
Samba3+LDAP, Samba4 domains (about 500 user accounts, GPO, Roaming profiles, a lot of other stuff). Standalone samba servers.
Docker, docker-compose, Jenkins, Ansible.
FreeNAS, TrueNas.

Dell servers, Dell PowerVault MD storages, HP servers, SuperMicro servers, and usual PC hardware.
HP, 3Com, Dell switches, no Cisco experience.

Shell, PHP scripting
I have a lot of other expertise. Feel free to ask.
