Art's Second Brain

Welcome to ASB — Art’s Second Brain.

This is where I think out loud. A digital garden of notes on actuarial science, AI workflows, insurance, leadership, and whatever I’m building or learning.

I’m Art (Arthapas Cheuasangpun) — VP Actuarial & Head of Retail UW at Tokio Marine South Thailand. I build AI persona frameworks, teach at Thammasat University, and study for CAS exams.
