Gemini's Development Practice - Commerce Backend Basics

This lecture doesn't just provide simple methods or answers; it offers opportunities to think for yourself using cases you might actually encounter in practice. I was satisfied with the quality of the lecture.

I feel like the questions I've always had about ambiguous parts of development are finally being answered. There is still so much to learn, but as I look at the requirements with the instructor and consider various perspectives, I feel like I'm starting to form my own decision-making process!

I was able to understand how you approach the general topic of commerce and how you interpret the realm of concepts. In particular, it was very good to see the philosophy about the work of 'development' throughout the entire lecture content. I would like to recommend this to those who want to become developers, but I especially want to highly recommend this lecture to 1-2 year developers or those with more experience who are confused about how to approach development work as a developer. Lastly, I was always curious about sample code while watching YouTube, and the lecture explained it in great detail, so it feels like my blockages have been resolved. I hope the next lecture comes out soon. Thank you for the good lecture.

The lectures were truly excellent, but I think the real gem is the code you provide. This code is a complete set that can be directly applied to real-world work in any domain. The concepts that I've been intensely contemplating for over 10 years as a developer are crystallized in this code. The project's layer structure, the role of each class, and even every meticulous configuration value are all the result of deep consideration. While taking the lectures, it felt like sitting next to you and developing together while pondering the problems, which was really wonderful. And just like someone I respect always used to say, there were countless moments when I thought "This is what I took the lecture for" (it really wasn't just one thing). Please continue to create many good lectures. I'm also consistently watching your YouTube videos. Thank you always.

I wonder if it's okay to write a review in advance, but... As someone who has been continuously watching through YouTube, this is so great. It feels like I've gained a good mentor..😭 I really love how you break down difficult development terms in a way that anyone can understand and guide us to think about them. Please keep making great lectures!

Hmm.. The first thought that came to mind after completing the course was "reason." Every code and design must have a reason, and this course constantly touches on those reasons. It makes me think more deeply even about parts I considered basic and took for granted (personally ingrained thoughts). You could say it builds the power of thinking, but I think it's also good to say it breaks the mold. Most importantly, the course is fun. As server developers would know, each topic and subject in the course has a satisfying depth to chew on and dissect 😆😆 Thank you so much for such a great course! If there's a follow-up course, I'll definitely purchase it. The downside is that I got so focused on the course that I missed mealtime and got hungry.. Oh, muscle loss..

After completing this course over about 8 days, I highly recommend this lecture. The biggest advantage is that each section helps develop the 'thinking power' itself - how to think about business requirements. The domain knowledge covered in the course will also serve as an excellent introduction for those interested in the commerce field. Personally, I believe this course maximizes its value not just by organizing content, but when you expand requirements and improve code on your own based on the knowledge and direction you've learned. I think this is what the instructor truly hopes for from students. Above all, the example code quality is good, and I was grateful for the many parts I could learn from and experiment with in that code. (Additional) If I may dare to give feedback, it would be great if you could cover technical 'exception handling' considerations in detail beyond business logic. For example, practical content like handling external network errors, retry policies, and how to consistently recover data when specific logic fails would be tremendously helpful if included in future 'intermediate' or 'advanced' editions!
