Tomasz – DevOps Engineer

Hi, I spent 5 years as a Sysadmin at Xebia before transitioning into DevOps, where I gained deep programming and cloud expertise in AWS and Azure. For the last two years, I’ve been focused on cost optimization, and now I’m channeling that experience into FinOps. In my spare time, I’m a music producer, guitarist, and runner.
