I'm a long-time professional Linux sysadmin, DevOps/GitOps engineer, entrepreneur and IT automation architect. I work mainly with open source automation tools like Puppet, Ansible, Terraform and Podman. Most of my professional work is done in public Clouds. I'm also a Red Hat Certified Engineer and work closely with Red Hat Finland and their partners. 

I'm also an archaeologist with a particular interest in artillery of the  Greek and Roman antiquity.
