quotation marks

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.

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.
