“The best thing about my experience in David’s class was the level of genuine interaction and the space he created for reflection and open discussion. He didn’t just teach concepts — he facilitated meaningful conversations that made me feel like an active participant rather than a passive learner. What really sets this experience apart from other courses or seminars is his patience and his ability to make every question, no matter how big or small, feel valuable. I never felt rushed or dismissed, which made the learning environment both empowering and comfortable. This approach helped me internalize the advanced concepts in a way that felt practical and relevant to my role as a Product Owner.”
