I worked at an SI company for almost 5 years as a Code Monkey, but I never used a framework to control it. I worked overtime and on weekends... I didn't have enough time or health, so I was busy resting whenever I had time. I'm working overtime tomorrow too.. When the screen design came out, I just made a bunch of controller service views. But this time, when I changed jobs, I got to deal with the framework in depth through REST API collaboration. I felt a lot of shortcomings, so I took the course. Since there's no overtime or weekend work, I can enjoy creating personal projects while watching the course. I took the course while applying the course content to my project. It was a very efficient course. There were times when errors would burst out, but when I looked at Stack Overflow with references, I was able to solve it without asking the instructor separately. I also took the REST API course. Thank you for the great course. It will be really helpful if you take the course while applying it to your own project that can be refactored, not just a project that goes through examples.
