I have taken an online course of Terraform and I liked it a lot. Ondrej was well prepared with many examples in Github. He was also willing to find a solution for other participants requests. I also appreciate the integration ideas with other tools (prometheus, gitlab, …). I definitelly recommend signing up to his courses.

The friendly Docker expert/mentor you want to meet! Ondrej did a two-day Docker workshop for our IT department in January 2020. In two days, he was able to go to quite a depth while keeping things reasonably clear for everyone. And we all welcomed the comprehensive materials he gave us for a later use. What I appreciated most was the numerous follow-up e-mails, checking on our team and offering help with any potential roadblocks. If you need somebody to help you kickstart or improve your Docker journey, I can only recommend Ondřej as your guy.

Ondrej is an experienced system architect and great lecturer who gladly answers any question thrown at him. Very enlightening Docker, Kubernetes and Terraform lessons.
Ondra is an experienced professional, fine lecturer and a great person. After attending his Docker course I was able to transform platform-locked legacy app to fully containerized app which enabled its comfortable continuous development.
