I didn't know I would get so into backend, but the more I do it, the more difficult and complicated it becomes, but I think I have a lot of fun in the process of understanding it. Of course, I think the instructor's easy-to-understand explanation is a big part of this. I was proud of completing the Nap series, but I was so sad that there was no next series yet. I think this is just the beginning. There are still many technologies left, such as Thymeleaf, JPA, Spring Boot, and Security, and I definitely want to learn from the instructor. The instructor, who is probably working hard on the next series, I am so so grateful, and I will be waiting for the great lectures that will come out in the future. (Sigh... When will the next lecture come out? I can't wait!!)
