About Me

Hi, I’m Piotr - a Technical Support Manager at Samsung, where I spend my days making Samsung Knox solutions behave exactly the way they should (and occasionally convincing them nicely when they don’t).

With 15 years in IT, I’ve worn quite a few hats: System Administrator, Solutions Architect, Product Manager… and, unofficially, “that person who prefers Linux whenever possible.” Give me a terminal, a clean config file, and a problem to solve - that’s my comfort zone.

I’m PMP® certified and comfortable across multiple operating systems, but Linux is where I feel most at home. Whether it’s optimizing system performance, troubleshooting tricky environments, or building reliable, scalable solutions, I enjoy getting into the details and making things work smoothly.

I thrive in cross-functional teams, turning complex challenges into practical solutions and continuously improving the user experience - ideally with a bit of elegance, efficiency, and maybe even a well-written bash script along the way.
