Hi, I'm Choi, a server developer at Kakao. Someone suddenly asked me for advice on filming a lecture, and after a few things here and there, I ended up giving some help. It's amazing to see the lecture actually being released like this 😊😊 I think I can see that the content I told him was incorporated as much as possible, which feels new to me. I hope that through this lecture, you all will fall in love with the charm of Kotlin.
