I'm a server developer working at Toss who participated most deeply in this MySQL course. Hong previously prepared and created a Kafka-related course together with Choi, and since that topic was really good and I also wanted to share my knowledge in a deeper way, I decided to participate like this. - Of course, I had participated indirectly or directly before, but I was more immersed and engaged in this course. Actually, I don't think simply covering MySQL content alone would have that great of a learning effect for you all. Currently, with AI advancement, AI actually writes queries better than we do. What you need to know here is "what aspects you can consider" and "what methods are available." I think the ability lies in knowing these aspects and knowing how to instruct AI accordingly. I hope this course will be very helpful to you all from that perspective. Please show lots of interest. Thank you!!
