Bio
Lukasz C.
I was working with Janusz for around a year in ITOps department. During this time Janusz was mostly responsible for implementing and maintaining Linux infrastructure and monitoring solution for the whole company infra. Janusz was always very professional and thanks to his experience (and patience) Linux servers infrastructure become not only updated and secure but also finally possible to be managed. He was always willing to share his knowledge and help others if needed. I can recommend him without any hesitation.
