Professional Overview

I sit with clients, find where money and alerts are leaking, and build the systems that catch it. My work is the part that makes AI trustworthy where money moves: a deterministic core decides anything that touches a money decision, the model only drafts language, and every run records which rule fired on which input. I also build the control that proves a check fired, because a suite that passes everything looks exactly like a suite that is not running. I came to this from the operator side, screening counterparties and wallets by hand at a crypto to fiat exchange for about six months before I built any tooling. PayPilot, a live failed-payment recovery agent, runs at paypilot.fly.dev and does not carry client traffic.
