Senior🎓
Top SchoolLiam Purvis is a Senior Data Scientist in New York with 11 years of experience building production ML systems that drive revenue and operational improvements. He has a track record of shipping end-to-end solutions—market-rate forecasting that produces ~36,000 daily forecasts, a company-wide A/B testing engine, and an auction-theory-backed automation that improved margins by ~15%. At Digit and Gopuff he designed high-impact models for overdraft prevention and multi-product demand forecasting, scaling to hundreds of stores and hundreds of thousands of users. His background blends rigorous statistics (UC Berkeley) and engineering (MEng EECS), enabling him to move projects from research clubs and POCs into monitored production. Notably, he has built large-scale data infrastructure—including a 4+ billion row database on Google Cloud—and co-invented a patented ML ensemble earlier in his career. Curious about both the right question and the right answer, he combines quantitative depth with product-focused delivery.
