Helping solo builders work smarter than teams with AI — author, educator, and your closest AI mentor
I teach n8n automation and Claude-powered workflows. 400+ one-on-one mentoring sessions, 30+ corporate trainings at Samsung Electronics, LG Electronics, KCC, and more. I'm not called a mentor because I'm brilliant — I'm called a mentor because I made the mistakes first. I don't sell answers; I share perspective.
Currently running ggplab — writing books, building courses, and running communities. 🇰🇷 Most of my content is in Korean.
