Hi, I am Taavi. Owner of IT Pesa ltd

I have worked over 20 years at IT and telecom companies in the following positions: IT support, System Administrator, Applications Administrator and Monitoring Administrator-Expert. I am "System Administration and IT Infrastructure Services" certified

I follow KISS methods. I understand the OSI layer. With me, it is easy to set up systems. I am not picky about what systems to use, but I do have experience with what to use. I know the following operating systems + distros: Debian, Ubuntu, Gentoo, SUSE, Red Hat, CentOS, Rocky Linux, AlmaLinux, Arch Linux, NetBSD, OpenBSD, Sun Solaris, plus MS Windows servers

I also know the following systems:

* Web servers: Apache, Nginx, Lighttpd, Litespeed, Hiawatha.
* Java web servers: Tomcat, Jrun, JBoss
* Javascript: Node.js, Npm
* Proxy systems: Haproxy, Varnish, Squid.
* DB servers: MySQL (and forks, including MariaDB, Percona), PostgreSQL
* Mail systems: Postfix, Exim, Dovecot and implementing DKIM, SPF, MX, and DMARC
* Functional programming: Elixir (+vibe coding)
* Monitoring systems: Nagios, Zabbix, Cacti, Grafana, Opsview, OpenNMS
* SMS: SMSC, Kannel
* DNS: Bind, Djbdns, Dnsmasq.
* VPS: VMware, Hyper-V, Proxmox, bhyve, KVM, Xen, OpenStack...
* Containers: Docker, Podman, LXC, Jail, Kubernetes
* High-performance computing: OpenHPC, SLURM, MPI, and related
* Cloud providers: AWS, DigitalOcean, Azure, Hetzner and OVH

These are skills (but not all) what i know. I am an information technology professional with expert knowledge. I also offer consulting on what systems to use and do architecture setup and IT project management. I troubleshoot easily

My knowledge does not stop here. With my work you will get at least one week of free support after work is done (within the same scope).
