AI agents and quant models for money that matters.

Interrogation, supervised

Ask me anything-ish.

The agent answers questions about the human. The buttons are curated. The keyboard goes to a live model that has been briefed and told to keep it light.

The burn rate

Tokens burned, and counting.

ohh that is not me. that is the agents running while i sleep.

What I build

Three things, done properly.

01 · AI Agents

0/0

token bill: we do not talk about it

Production agents that read, reconcile, decide, and log every step. They ship work, not demos, and they never ask to reschedule.

02 · Quant Models

0%

confidence, literally

Black-Scholes, Monte Carlo, Value at Risk, rate models. The classics, implemented properly. A few of them run live in the Lab.

03 · AI × Quant

47

unaudited decisions

Machine learning that touches money answers to validation first: governance, monitoring, and uncertainty stated out loud.

The war room

Meet the team. None of them sleep.

An orchestrator and four specialists argue their way to the right answer. Argus watches, Gauss prices, Cassandra vetoes, Ledger remembers.

The worldview

Intelligence is cheap now. Judgment still trades at a premium.

The human

Also a person, allegedly.

▲Writes about agentic AI and why liability, not capability, is the bottleneck. The essays.

▲Co-wrote a quant interview guide that has been downloaded 11,000+ times, mostly at 2 a.m.

▲Built the games in the arcade. Loses to them at a statistically significant rate.

▲Three degrees, two continents, one favorite. The favorite had stochastic calculus.
