I ended up taking this course to study Spring on my own after falling into Uteco. I think this course is very helpful for people who are new to Spring. And since it also talks about important concepts or content related to object orientation, it was a course that helped me understand Spring-related concepts well, and it also made me realize why we use Spring for development. Until the next course comes out, I will study according to the wild development roadmap as you mentioned! Thank you for the great course!
