I am an accomplished author and expert in Apache Kafka, having written two highly acclaimed books on the subject. These publications have garnered significant popularity among Kafka users and developers alike. Currently, I am a Data Engineer at SK Telecom, where I specialize in operating Kafka clusters and managing diverse data processing tasks using Kafka.

I lead the largest Kafka user group in Korea, dedicated to expanding the understanding and application of Kafka through regular meetups. These events facilitate the exchange of knowledge and experiences among Kafka users across the country. I actively share my expertise through seminars, blog posts, and other channels, ensuring that both new and seasoned Kafka enthusiasts have access to valuable insights and the latest developments. Engaging with fellow Kafka enthusiasts is a passion of mine, and I find great joy in fostering a vibrant and knowledgeable community.
