I am a working backend developer. Everything I feel when watching your lectures can be summarized in one word: "Empathy." I relate to every single thing you say, and I strongly agree with your point about Java vs. DB—that if the DB is well-designed and structured, the difficulty of development significantly decreases. Compared to your other courses, this one took me a bit longer to get through and was more challenging to understand. However, being able to firmly grasp the fundamental principles of how subqueries work made the course worth the purchase alone, and you've truly opened my eyes to indexes. I will continue to follow your lectures and strive to become a better developer. Thank you for the great course.
