Hello. I first encountered Spring through Kim Young-han's Spring lecture. I started studying backend without even knowing Java properly, but through Kim Young-han's lecture, I was able to learn the concept of object-oriented and how to use Spring Boot, and I was able to understand Spring Data JPA clearly. I am especially grateful that you helped me grow from a backend beginner to this point. Your teaching skills are also great, and since I studied in a wild way, I think I learned and gained a lot quickly. I am really grateful. I will continue to listen to your lectures diligently and study hard!! PS. I like the friendly Gyeongsang dialect! ㅎㅎ
