I really enjoyed it!! From a practical perspective, I was able to gain insight into how to handle business logic, layers, and modules, and I think it's a topic for discussion with colleagues. However, I have one suggestion that I'd like to leave. There are many videos on YouTube with good topics, but if you have a lecture format that explains certain ideas or principles like this lecture, rather than a Q&A format, I would like you to upload it to Inflearn, whether it's this lecture or another lecture. It has a subtitle function, and you can use study notes, etc. From the learner's perspective, it's better to have content gathered on a learning platform! I think it would be good if Q&A-format videos were uploaded to Inflearn, but I think it would be better if they were collected separately.
