I completed everything from the meetup video to lecture 3 without missing a single one, and I think this is the most practical course that can be immediately applied to real work. You expressed in clear language what I had only vaguely felt about architecture and code quality, which was a great help. I'm also using the content from this course in AI agent instruction files like CLAUDE.md, and I can feel that the quality of the code being written has improved significantly. I hope to meet you again with another great course someday. Thank you for the excellent course.
