I help companies build systems that learn from data.
I run marketing experiments that quantify what actually matters, and build AI systems that turn complex data into clear decisions. I've led data science at Tuft & Needle (where experiments drove $5M+ in incremental revenue) and Your Super. Currently running Deciding Data. Master's in Applied Statistics, 10+ years in the field.
