I started learning development for the first time in early 2024, beginning with the Java Basics course. By summer, I had studied the Java Intermediate course and followed the Spring roadmap, while consistently studying operating systems and computer architecture in between. I was able to pass the SSAFY selection, and thanks to Young-han's lectures, I got accepted into the Java track and have now successfully completed the program. After completion, I continued learning up to Advanced Part 3, and now I have confidence and certainty, whereas I was anxious when I first started with the Basics course. If someone asks me in the future, "Who did you learn Java from?", I will be able to proudly say that I learned from instructor Kim Young-han. Thank you sincerely.
