How Spring Boot works and how its internal structure is structured, I remember and liked the way you explained it from scratch, making it yourself, and then replacing it with the functions provided by Spring Boot. Even for me, who has been away from the server for quite some time, you explained it well in an easy-to-understand way, and I learned a lot from watching the lecture about how to approach it and become a developer who advances, not just a good way to do it. Thank you!
