I have completed the course. The quality of the lectures is excellent, and even though it's an older course, the fact that you explain things using fixed versions without constant changes is very helpful. Honestly, even if things were to change, it wouldn't matter much since we have AI now. I had a lot of things to test in a Docker environment at work, and this was a huge help. I've tried many other courses before but stopped because they weren't very helpful; however, I followed your roadmap and finished all your lectures, and it was worth every penny.
