This feels like a scam/spam to me.

If I open my Instagram right now, I will see thousands of those courses. All of them making mistakes about what a masterclass is, all of them talking about "modern" stacks and lacking a lot of content.

To put into perspective: 2 of the 3 courses that I've enrolled missed the "how to put in production mode" part.

But don't get me wrong, I like what you are doing. It is just that I miss the "real advanced" part. All of them seems to teach the same thing, in the same speed.
