I'm a knowledge sharer who works as both an interviewer and developer at Kakao. This time, together with Hong, I've prepared a course that introduces various perspectives on distributed environments and several patterns you can reference when structuring your projects. I've tried to incorporate as much as possible the perspectives from which I typically ask questions in interviews. Representative examples include: 1. How do you debug in a distributed environment?? 2. Please explain the patterns you know. 3. How do you conduct testing according to architecture?? If you focus on these topics, you'll find this course even more beneficial. I hope you gain many insights. Thank you!
