“Getting Started with Claude Code the Right Way” was co-written by two working developers.
After working on Naver’s log platform and the Air Force’s real-time control system, he now leads an AI startup. He runs the developer education YouTube channel 「큰돌의 터전」, which has 25,000 subscribers, and is also an IT author who ranks in the top 0.1% on Baekjoon, contributes to the open-source project Mocha.js, and wrote a bestselling CS interview book.
I currently develop server software at KakaoBank. I previously worked on growth product development at Kurly and AI chatbot development at TUNiB, and before that, I ran a software development startup myself. I won the Snowflake AI & Data Hackathon 2026 and reached the finals of multiple hackathons, including the OpenAI Ralphthon and Cursor Hackathon. I also published a paper in the ACM international conference DEBS 2022 Grand Challenge. As a JVM-based open-source contributor to projects such as Spring Batch and Jackson, I continue to give technical presentations at various companies, universities, and conferences.
