Summary
👤
SeniorBill Freeman is a Data Scientist with 12 years of analytical and research experience and 5+ years focused on building data-driven products that solve business problems. He currently applies production ML and analytics at Kohl's while co-founding PureSkill.gg, an AI coach that extracts and analyzes CS:GO replays to give prescriptive, actionable feedback to players. His background spans retail assortment optimization, recommender systems, and high-throughput document classification, and he has a strong foundation in turning messy SQL-based datasets into reliable features and tools used across teams. Prior to industry roles he earned a PhD in Astrophysics and created open-source pipelines and novel methods for separating galaxy and outflow signals—experience that underpins his rigor in experimental design and model validation. Notably, he scaled game-replay collection to multiple terabytes and pioneered algorithms to quantify individual player impact, blending scientific methods with product-driven machine learning. Based in Austin, he combines academic rigor, startup grit, and practical engineering to move ML projects from prototype to production.
