Overview

20 years in data science and analytics, the last 2 at General Motors, where I lead the recommendations team. Replaced 106 hand-built dashboards with one metrics layer people trust. Moved the homepage from rules to a learned ranker. Before that: Lockheed Martin and Stripe. Most at home with ranking and PyTorch. Plant-based cook and baker.
