This is one of the best lectures among the best lectures. First of all, I came here because I wanted to use fast API, but while learning asynchronous programming, I realized that I am still a person who is lacking in many ways. However, the instructor explained it in detail and in an easy-to-understand manner, so it was a very satisfying lecture. I would pay and listen even if it cost more than 100,000 won, adding a little exaggeration... This lecture covers everything from back-end to front-end and server deployment. After listening to this lecture, you will be able to expand your horizons by gaining similar experience before doing something difficult like Spring framework, and it will be a good specification for those who have never done server deployment before. I will diligently review the contents that the instructor taught me and develop them into projects to make them my knowledge. Thank you again ㅎㅎㅎ Can I ask you to teach Spring Framework next time.. ㅠㅠ You really teach so well, thank you!!
