I think this lecture covers the really important parts of backend from A to Z well. It was good because it was easy to learn for even those who are new to backend, from setting up the development environment to ERD, DB, SQL, and even Prisma, which is used a lot in the field these days. I really liked that it taught everything from the most important authentication in backend to creating simple CRUD and even AWS deployment. The instructor definitely worked in the field, so it was really helpful because he taught me the knowledge that is absolutely necessary for practical work like Swagger. While other backend lectures focus on theory, this lecture covers both theory and practical work, so it seems like a great lecture for prospective backend developers preparing for employment.
