I am a new developer working in the backend field. It took me a little longer than I planned because I was taking it while working, but I was able to complete this course by using my commute time and weekends. :) To summarize in one sentence, it was a very useful lecture. Until now, it was really hard to look at how the API code I wrote works only from the perspective of the Spring architecture and the network perspective, but now I can expand it to the network and think meaningfully about how to write application code depending on the environment. Recently, based on the lecture content I learned so far, I solved a chronic issue that the development team had not been able to fix well! I was so proud. This time, I want to properly understand https, and my goal is to complete the ‘SSL and Minimum Cryptography Technology by Memorizing’ course. Thank you so much for the useful lecture.
