Domains of Expertise
Due to my interests in new technologies since my early years, I decided to join an IT company right after I left school. My very first job was a Monitoring Specialist at T-Systems Slovakia. While it was good for start of my professional career, I wanted to improve my knowledge in the Linux/Unix areas and after 3 years I applied for a 2nd level UNIX/Solaris Administrator position. I succeeded and got the pleasure to work with some amazingly skilled engineers who helped me to improve my knowledge in various areas. At that time I became interested in scripting and automation where a sysadmin position offered plenty of opportunities.
At the end of 2011 I decided to move to the Czech Republic and joined OKIN where I have been working as a Junior UNIX Administrator. Thanks to my past experience I was promoted to a Senior UNIX Administrator in just 9 months. During my senior position I developed several internal tools/scripts that are still actively used by the whole teams.
In 2014 my team leader left the company and as I had been her deputy for almost 2 years, I was promoted to Team Leader. I was managing the team for 1 and a half year and played a major role in transforming the team from 8x5 to 24x7 which was unbelievably difficult but was a very good challenge.
In October 2014 I was approached by the Managing Director of OKIN to help start a new project of Cloud Services. I have done over 400 interviews in first 6 months and helped to fill about 100 positions - doing all this while still running the Service Desk team.
In September 2015 we found my replacement team leader to take over from me for my old team and I became the Team Leader for Linux and DBA teams within this new project. I've built team from scratch to around 20 people in a 24x7 environment in Tier 1 & 2.
In August 2016 I got a chance to work for Tieto company as a Line Manager for Windows Tier 3 engineers and decided to leave Okin and pursue this new challenge.
After 9 years in operations I felt like I need a change and as of March 2018 I am now leading several
teams of DevOps Engineers and Software Developers.
In this role I am split roughly 70:30 between technical and managerial role.
- As a manager I am responsible for 5 agile teams totaling roughly 30 people.
- As a technician I am part of DevOps team working primarily on apps/tooling/automation in C# and
Typescript (Azure Functions, Azure DevOps extensions, web apps, desktop apps, cli tools) and Linux
automation in Python/Ansible (mainly from RedHat family).
As of October 2022 I work as a DevOps Engineer for Veeam Software. I have decided to switch fully back to technical role. I now focus on DevOps (pipelines, automation, cli apps, APIs) and primarily work in .NET (C#) and Ansible with heavy scripting in Powershell, Python and BASH.
