Having only used Spring Boot, I started using Prisma and NestJS for the first time at my company, and this lecture allowed me to apply it to my work immediately. In addition to the basic functions, I was able to learn technologies that are mainly used in the field, such as pessimistic lock implementation, shopping cart optimization using Redis TTL, and EDA with Kafka. In particular, the process of implementing backend design and design patterns into actual code was explained in detail, which was a very useful lecture that allowed me to immediately apply the concepts I had only encountered in theory to the field. Thank you for the great lecture.
