I have been following Stefan's YouTube channel for many years and I always liked his beginner-friendly approach. There are so many people out there who leave important steps out because they assume you know how to do it, but Stefan always goes the whole 10 yards with his tutorials and he leaves no steps out.
This course was really helpful to understand pfSense without having any prior experience with firewalls. Stefan is explaining this topic in a very approachable and easy-to-understand way.
Very structured and easy to follow. Nice coverage of even relevant topics around. My personal highlight is the result of the course. I love the customized terminal so much! A good looking and functioning environment provides so much more fun during work!
I build indie products in public and teach developers how to ship faster with AI tooling. Reach out for partnerships, product feedback, or collaborations.
