I'm a non-major who just started development. I'm hoping to get a job in the development field, so I was recommended Kim Young-han's lectures by a family member in the field and decided to listen to them. I've always been curious about development, but there were many parts I couldn't understand even after reading various books, so I gave up at the very beginning every time. However, Kim Young-han's classes were really smooth, refreshing, and enjoyable. I usually don't concentrate well and lack consistency, so it took me two months to finish the lecture, but after finally finishing it, I feel so relieved and it feels like I've taken my first step towards getting a job. Thank you so much for providing such a great lecture for free.
