I study with the book and review with the lectures, and it's really great.

This was a lecture where I could experience the design thinking of a "true senior" based on SOLID principles. I initially focused on just watching the lectures because I felt my concentration slipping when trying to follow along with the examples, but the level of immersion from the midpoint onwards was incredible. Before purchasing, I saw the game examples and wondered if it might be a light course, but that was a misjudgment on my part. It was a lecture that allowed me to develop design thinking and perspectives that are hard to experience in practical work. I look forward to the future where I will have grown to the next level after reviewing this. Thank you for the great lecture.

This is a great lecture that every developer should watch. I'm leaving with a lot of great insights!

This was a truly satisfying lecture!
