First of all, as a 5-year system engineer, thank you so much for leaving honest and specific feedback based on your practical experience. As I prepared the lecture, I aimed for practical integrated architecture design and practice, so the opinions from an expert's perspective are very helpful to me. I am very sorry that the explanation of the setting process, system linkage, and architecture design intention was insufficient because I focused on implementing actual projects for those who have basic knowledge of RabbitMQ, Kafka, and Redis. As you said, I deeply sympathize with the fact that I focused only on running Python code after Docker deployment, and that more background explanation was needed for "why this design was made." I will definitely reflect this in supplementing the lecture or providing additional materials so that even those with practical experience can be more satisfied. I am curious if you felt that way even in the practical lecture where I explain the code, theoretical parts, and practical parts together, as it is not just execution without explanation in all the practical lectures. In the final practice, we also drew the system design together with diagrams and explained the flow and architecture together, and I would like to ask if there was a problem with that part and receive feedback. Also, I think the expectations and actual contents were different due to the lecture difficulty being marked as beginner level, and although I considered students of various levels including beginners, adjustments were needed in terms of the depth and speed of the practice. I will reflect this more clearly in the lecture introduction to reduce confusion among students. Thanks to your valuable feedback, I think I can develop the lecture in a better direction. Thank you. I will revise the lecture level from beginner. And one more thing, As a small token of appreciation, I would like to give you a free coupon for my system design lecture. Please leave your email address and I will send it to you.

Hello. I was frustrated and wrote a review in the middle of listening to the lecture, and I appreciate your reply. I took the lecture because I wanted to improve my understanding of the company system I'm working for, but I wrote the review because I was disappointed that there wasn't much of this content in the lecture. I apologize if there was some harsh language. Thank you.
