Senior🎓
Top SchoolSam Steingold is a Senior Quantitative Analyst and PhD mathematician with 27 years of experience translating advanced mathematical modeling into production-ready data science systems across finance, advertising, and security. He combines deep expertise in stochastic processes, Bayesian modeling, graph and text analytics, and ensemble methods with hands-on software engineering in Python, R, C/C++, Scala and distributed platforms like Hadoop and Spark. Sam has built and led data science teams, mentored contributors to large open-source projects, and contributed to notable repos including Vowpal Wabbit and Emacs data-science tooling. His work spans the full ML lifecycle—from research and trading-system design to deploying robust production models and embedding huge Boolean expressions for ML at Amazon. Comfortable both in low-latency financial environments and product-facing analytics, he brings a rare mix of formal mathematical rigor and pragmatic engineering craft. Based in New York, he often operates at the intersection of open-source collaboration and proprietary system delivery, having done “data science before it was called data science.”
