Senior Data Scientist
Senior data scientist — ML & experimentation that moves the metric
About
I turn business questions into experiments and models, then prove they worked. Five years across marketplace and fintech — currently owning recommendations for 4M monthly shoppers and the A/B testing framework that keeps every launch honest. I obsess over clean statistics and recommendations a non-technical exec can act on in a minute.
