About me

First of all, I love everything about IT. Ever since I crashed my first 486 PC I knew that software and hardware will be my passion. I spent days and nights of my youth with the lovely sound of floppy drive clicking and 36k modems purring. I was thrilled seeing “Hello Zeljko” displayed on white 13” CRT as I learned my first programming steps.

I truly believed that IT will transform the world as we know it, and I enjoyed technology progress and transformation even when I was mocked for carrying “huge bricks” (Palm PC/PDA’s), and not “sleek and elegant” micro mobile phones of the time.

During faculty I started my first contract as I was eager to learn more about IT. I learned a lot about security (thanks to unsecure Windows Server 2000), SQL database management and availability (cloud based medical software with HA need). My first job was also a time when I earned my first IT Pro certification – MCSA (Microsoft Certified System Administrator).

My second job is my current one, and so far it gave me a plenty of space to grow as a person and professional. I started as senior system administrator, advanced into engineering position with main goal to align companies’ goals, needs and risks with technology.

I happily accept challenges of the various projects in/outside of the company. Diversity of projects really helped me get more mature in combining various solutions and technologies (HA, DR, SAN storage, web/IIS, security…) and gaining project leadership skills.

I got opportunity to further advance my Microsoft certifications, add Cisco and security skills to my ever-expanding portfolio.

Most recently we completed implementation and certification for ISO 27001. We are exploring various cloud services and options for our workloads while also trying to automate and monitor various everyday IT processes with help of scripting.

Even when I leave office, I continue to explore IT at home. Red Hat, Docker, VMware vSphere, Azure are some of the technologies I enjoy learning and exploring… IT security is also one of the things that keeps me up at night.

I also try to share bits of my IT experiences via this blog.
