About Me
I'm a financial engineering and accounting student at Washington University in St. Louis. Most of my time goes to markets, machine learning, and the seam where the two meet — pricing, portfolio construction, and the messier question of when a model actually deserves to be trusted.
I passed CFA Level I and I'm sitting for Level II in 2026. Alongside coursework I run sales and go-to-market for Text Maddie, an AI sales agent that works over iMessage, which has been a fast education in how a product finds its first real customers.
I care about building things that hold up and explaining them without hand-waving. This site is where I keep that work: a record of what I've shipped and a shelf of what I'm thinking through. If something here is worth a conversation, get in touch.
