When I was stumbling on some of his output it unfortunately felt very click-baity, always playing on your FOMO if you didn’t set up/download/buy the next best thing until the other next best thing in the video after.

In other words, I think he’s cool to check out to get to know of a thing, but to get a deeper level of understanding how a thing works I would recommend written materials. There are good caddy/nginx tutorials out there, but a linux networking book will get your understanding further yet.

If it has to be video, I would at least recommend a little more slowed down, long-form content like Learn Linux TV.
