Founder of CMDSPACE — I design the knowledge structures that make AI actually work.
I run a 10,000+ note Obsidian vault as a daily agent harness: CLAUDE.md/AGENTS.md system files, an LLM-maintained wiki, and slash-command workflows — all published as open specs and starter kits below. By day I teach executive AI programs (incl. LG chairman-group and C-suite coaching — 150+ lectures in 2025) and write the Korean newsletter 더배러 The Better. Author of 옵시디언 프로페셔널 노트 (Obsidian Professional Note, 2026).
The thesis in one line: models converged — your context is the moat, and a markdown Second Brain is the harness that makes AI work for you.
