Following Part 1, I've finally completed Part 2! In this Part 2 lecture, technologies I was always curious about (such as video player implementation, shopping cart, payment processing, Sentry integration, etc.) were naturally explained with actual code, which was truly enjoyable and beneficial. As a junior developer, there were many parts I could immediately apply to actual work, and I also enjoyed learning by following along :) The lecture explained the design intentions and reasons for choices, allowing me to go beyond simply typing along and truly "implement with understanding." Thank you for creating such a great lecture! I look forward to your next one 🙌
