Hello, Younghan! I'm a junior developer working as a backend developer at a very early-stage startup. While working, I've been following the Java -> Spring -> DB curriculum, and although I'm not usually the type to leave reviews, I was deeply moved by the final episode "What's Next" in the DB introduction course, so I'm leaving this review. In my case, since the company is very small, it's difficult to receive advice or reviews from senior developers about good code or design, but I'm solving a lot of these issues through your courses. When I look at job postings or listen to other developers, their tech stacks are incredibly impressive, but while working, I'm constantly wondering whether those stacks are really necessary, whether those technologies are truly needed for our company right now, and if there are easier ways to solve problems. To get answers to these concerns, I need the process of seeking advice and learning from truly capable senior developers about what technologies are needed in what situations, and I'm getting many answers to these concerns while watching your courses. When you create other courses in the future, I would be grateful if you could share your many insights and practical experience so that I can continue to find answers to these concerns. Thank you always for creating such great courses!
