Tjong Wu builds the kind of systemsa controller would trust — financejudgment, shipped whole andshown in the open.

A finance & control professional who designs and ships agentic systems. The thread through all of it is the same instinct: take a judgment that usually lives in a person’s head — a risk read, a go / no-go, a fair rent — and make it transparent, rule-grounded, and reproducible.

Most people can prompt. Most controllers can read a ledger. The work here is what sits in between — models and agents that earn trust the way a ledger does, built end to end and left open to read.
