Summary
👤
Senior🎓
Top SchoolWalter Ullon is a data scientist with nine years of experience building the infrastructure layer that turns raw data into production decisions—pipelines, ML models, and productized tooling—currently applying that expertise at Polly. He has led cross-functional teams to launch no-code ETL products and steered multi-million dollar data science roadmaps while also delivering client-facing ML solutions that cut processing times and errors significantly. At EZOPS he bridged product and engineering, shipping an NLP rule-discovery app and high-confidence classifiers that materially reduced operational workload and accelerated sales. Skilled in production ML, feature engineering, explainability (SHAP, model cards), and stakeholder-driven requirements, he excels at simplifying complex data needs and translating them into revenue-generating features. Based in Easton, PA, he combines hands-on modeling with product strategy—often shrinking feature sets dramatically to boost robustness—and brings a practical, client-focused lens to fintech problems.
