Mr. Baek Gi-seon! I watched it so informatively~ Honestly, I didn't study Spring properly and develop it. I developed it by looking at the developed source code and guessing (...reflection...😔) Mr. Gi-seon, I was reading the Spring Boot reference on YouTube, but I was about to give up because I didn't know much... but I saw a lecture that was distributed for free and watched it. As I watched the free lecture and learned little by little, I wanted to know more! After watching the lecture and going to work, every day feels like a different source code. I also saw the areas for improvement, so I'm writing them down in my notes. (I think it will have a positive effect on my evaluation😉) Thank you so much. I'm going to keep listening to other lectures~ And I'm so grateful for the discount~^^ I'll work hard to become a developer who knows and develops~!!
