I worked as a C++ application developer for several years at a company, and then I switched to the web backend domain through a job change. I really wanted to do web development since my college days, so I participated in Motsado and worked there for a year, but at that time, the backend field was too difficult for me to understand. However, after taking the Roadmap lectures, I thought that I could work in this field. Thank you so much. You explained it in detail one by one, and I think I understand it little by little as I follow along with the examples. And since you drew the overall roadmap, I worry less about the direction, and I can reinvest that time in the lectures, so it seems very efficient. Thank you so much for providing such a great lecture.
