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