The lectures you uploaded were even better because they went beyond simple concepts and covered practical knowledge such as practical trends and solutions to problems that can arise in the field. And as you expanded the examples step by step and compared the before and after to explain the pros and cons in detail, I was able to check the internal workings and the development flow so far at a glance. I was so grateful because I could constantly feel the consideration for the students taking the course, such as adding comments or making it by version to make it easy to review. And I hadn't thought of it, but at the end, you gave some sincere advice for the future of developers, which really helped relieve my vague anxiety. I'd like to actively recommend Kim Young-han's Spring Complete Conquest Course to people who are thinking about moving to Spring.
