I’m a Linux System Administrator and DevOps Engineer with a focus on site reliability. I build and maintain cloud infrastructure, automate repeatable work, and investigate the failures that get in the way of dependable services.
My work spans Linux servers, Ansible provisioning, containerized applications, web infrastructure and MySQL. I use monitoring, logs and performance data to understand problems, improve alerting, and make systems easier to operate and recover.
My homelab is a place to put those skills into practice: connecting Raspberry Pi services, private networking, media storage and Home Assistant, with custom Python integrations and Zabbix monitoring across home and cloud systems.
I use AI tools such as ChatGPT and Codex as part of my engineering workflow—for exploring solutions, writing and reviewing scripts, investigating incidents and producing documentation. I review the changes, validate the results, and take responsibility for the systems I run.
Built an Ansible-managed Ubuntu workspace on GCP with access through a certificate-authenticated VPN. Persistent Byobu / tmux sessions, SSH and Mosh support work across devices, with repeatable configuration, backups and automated Git / CVS update reports.

Created a Python service that turns a published school menu into an iCalendar feed for Home Assistant. It parses Croatian dates, retains previous menus, preserves the last good feed on fetch errors, and refreshes the tablet dashboard automatically.
