Summary
👤
Senior🎓
Top SchoolSean Mills is a CTO and quantitative leader who builds state-of-the-art AI/ML underwriting models, manages portfolio risk, and forges strategic partnerships in consumer credit. With a PhD in Astrophysics from the University of Chicago and postdoctoral research at Caltech, he brings eight years of experience applying N-body dynamical modeling, Bayesian inference, and custom C/Python tooling to extract weak signals from noisy time-series data. He moved from interpreting exoplanet interactions to modeling financial systems, translating principled Monte Carlo and probabilistic methods into robust production models. Based in San Francisco, Sean blends research rigor with product-focused engineering, routinely shipping production-ready analytics and risk systems. An unusual strength is his track record of building computationally efficient, low-order models that capture complex dynamics—whether planetary or portfolio-level—enabling scalable inference where full simulations are infeasible.
