I took this course while being familiar with Java and Spring, but without much experience using JPA, Redis, and Kafka. Since the course itself doesn't dive deep into the technical details of the tools used, I didn't have much trouble following along by pausing and looking things up whenever I encountered something I didn't know. (To be honest, personally, I think it would have been even better if the explanations were a bit more detailed haha...) Still, I liked how you explained the simple architecture and how to utilize the technology to solve problems. Since I only use very legacy technologies at work, I was curious about how to handle high-traffic situations using modern tech, and it was very helpful to learn through hands-on practice. I will study the technologies used in the course further! Thank you for the great lecture 😊
