The explanation of backend and frontend concepts early in the lecture was good. It felt like the concepts were starting to click. Junior PM/PO professionals focused on service planning will certainly find it helpful too. As for the subsequent project lectures, I didn't follow along; I just quickly watched them while exercising. I initially tried to, but figured the instructor's implementation methods and error cases would likely differ from mine anyway. My plan is to quickly skim through the projects first, even if I don't fully understand them, and then rewatch them later for reference. Thank you for the good lecture.
