I listened to the lecture well!! Now, I think it's okay to call this roadmap the regular curriculum for the Java backend course!ㅎㅎ In the fall of 2021, I suddenly started developing web backends at my company~ I had been developing mainly Windows clients with C++ and C#, so I actually didn't want to do Java web development. At that time, I personally didn't have a good perception of web development.. I tried learning it briefly in the past, but at the time, I had very little experience using Java and Eclipse, so I was even more reluctant. Still, I had no choice but to do it because I was told to, and while looking for books and lectures to learn, I came across Kim Young-han's lecture about two years ago! There were many materials and lectures, but this lecture had really good reviews at the time, and I liked the fact that I was learning about Spring and JPA from one person. And when I actually listened to the lecture, I was surprised that it was this easy to learn and that I could take this level of lecture at such a low priceㅋㅋ Even while listening to the lecture and applying it to toy projects and practical work, there was no frustrating part that I usually experienced in the past! And at that time, I liked the lecture so much that I kept recommending it to developers around me.. Now, there is no web developer I know who has not taken this lecture~ It is amazing and I feel proud that I have contributed to its success..ㅎㅎ In my company, there were no web developers, but the number increased little by little, and now all of the backend developers are taking this lecture! I bought it every time a new lecture came out and watched it here and there, and I finally finished the roadmap! I plan to watch it again quickly to review it~ I want to tell you that I was able to study really enjoyably thanks to this lecture, and I am grateful every time I watch it because you made such a good lecture. I am looking forward to the upcoming lectures. Stay healthy!!
