Overview

9 years in data science and analytics, the last 1 at Feedzai, where I work on the pricing team. Wrote the metric definitions the leadership team reviews every week. Before that: Novartis and Klarna. Most at home with price elasticity and optimisation. Outside work: long runs and longer podcasts.
