I think the biggest feature and advantage of Baek Gi-seon's lecture is that it doesn't just provide the right answer to the problem, but also teaches you how to find and choose a method to solve the problem. In most of Baek Gi-seon's lectures, the parts where he shows you the moments when he makes a mistake or encounters an unexpected problem, finds a method, and solves the problem through debugging without editing, made me feel like I was doing live coding with him, and it was good because I could see how he views the problem and solves it. When I first started developing, I only had a vague dream of becoming a Spring developer. I didn't know what kind of problem Spring technology was created to solve, what kind of value it provides to our developers, and how it became so popular. However, two years ago, I happened to come across Baek Gi-seon's YouTube channel, and from the first REST-API lecture at Inflearn to the current Effective Java lecture, I realized that technology is not everything when living as a developer, and I reflected on it, and I focused on learning the unchanging fundamental technology and knowledge that are the foundation of many technologies that change like Spring. Let me talk about the lecture atmosphere briefly. In the past, I felt that it was somewhat stiff and a little unfriendly, and I thought that there would be quite a few people who would be sensitive to this, but now I feel that the overall lecture atmosphere and lecture quality have greatly improved. It's the best. Lastly, after communicating with Baek Gi-seon through YouTube and Inflearn for two years, I got a job this year and am happily working at the company. I am truly grateful to Baek Gi-seon, who helped me establish my identity as a developer and realize how to study, and to Inflearn, who helped me easily access such a great lecture! I look forward to better lectures and better services in the future!!
