DARKO DRAZOVIC
Certified Linux Engineer and Sysadmin with over ten years of experience in IT systems
administration, including Windows workstations and servers, virtualization, networks, monitoring, Oracle DB, IT
security, WordPress, IT support, and consulting. Essential skills and technologies in my portfolio include Linux,
Ansible, shell scripting, and system administration.
I am interested in learning and mastering Docker, Kubernetes, Cloud-Ops (AWS or Azure),
Terraform, and automation through hands-on experience. Beyond this geeky stuff, I am a big fan of table tennis, chess, and movies - mostly
horror and fantasy.
