How I got here
Poker first, then the part of finance that looks like poker
Poker taught me to reason about hidden information before I had a name for it. You act on a distribution, not a fact — and the discipline of separating a good decision from a good outcome is the same discipline a research process needs. Counterfactual regret minimization is the formal version of that instinct, which is why so much of this site is spent taking it apart: Kuhn, then Leduc, then the neural variants, each one small enough to hold in your head and watch converge.
Markets were the natural next table. I research alphas on WorldQuant BRAIN, where I reached Expert level in 2026 Q2 — cross-sectional ranking, neutralization, turnover control, and the automated pipelines that keep candidate signals flowing instead of arriving in batches whenever I think one up. The bottleneck stopped being ideas and became how carefully I screen them. Two BRAIN competitions have placed me 1st in Thailand.
Along the way I have joined BRAIN roadshows at Khon Kaen and Chulalongkorn, helped run quant research nights, and mentored a friend from software engineering into quant, who now represents Thailand at IQC. Teaching the material is the fastest way I know to find out which parts of it I only thought I understood.
Everything published here is a study artifact rather than a product. The solvers are real and the numbers are computed live, but the notes are mine and the mistakes are too — where a page is unverified, it says so at the top.
