Top School

John Peach is a Principal Data Scientist with over a decade of experience turning ambiguous problems into production-grade machine learning solutions across startups and FAANG-scale environments. With advanced training spanning mechanical engineering, kinesiology and data science, he blends rigorous modeling, software engineering and domain insight to build reproducible, data-driven products and developer-friendly tooling such as Oracle's ADS SDK and Feature Types. He has led programs that institutionalize best practices—launching Amazon’s Machine Learning University in Irvine and an Alexa-wide Data Science Excellence initiative—while mentoring many to transition from academia to industry. A prolific educator and community builder, he co-organizes Southern California’s largest R meetup and authors practical tutorials and notebooks for OCI Data Science. Equally comfortable with petabyte-scale governance and low-infrastructure startups, he is known for creative curiosity and a track record of surfacing "hidden secrets" in data that materially improve customer outcomes.
