Field notes from a builder, operator, and AI strategist in Korean tech.

What it is
Minbook is field notes on Korean tech, written from the operator's seat. The work organises into three streams: analysis (AI market, monetisation, Korean SaaS economics), agents (Claude Code anatomy, agent loops, orchestration, self-tuning), and build-logs (WICHI, MMU, Self-Tuning Loop — the products in the open). Full KO / EN parity.
Why it matters
The analysis comes from operating, not commenting — running products in production and consulting enterprise GenAI strategy at KT. Few Korean tech writers work from that vantage point, and fewer maintain a parity bilingual surface so the same argument lands in both Korean and English readerships.
