I had seen Programming Zombie mentioned in other YouTube videos and various lectures, so when I saw Programming Zombie's character, I purchased without hesitation. Honestly, I thought you would teach mobile app development methodologies or how to create with vibe coding. However, that expectation was completely shattered and replaced with such an excellent lecture that even though it's a bit pricey for Inflearn, it wasn't a waste at all. You shared really great tips and know-how, and it feels like you've set a milestone for how to develop and market going forward, and how to build a development environment. Now I'm ready to start in earnest. I will work hard until the end so that the day I can quit my job like Programming Zombie might come.
