4/2018 - today

Director of Data Science

Billie is a breakthrough fintech startup that aims to create a new standard for business purchasing. I've started as a hands on data scientist at Billie working on the risk engines and later shifted focus to ml-based internal products. In the end the leads of the teams that were responsible for

• credit scoring models,
• fraud prevention systems,
• machine-learning based internal products used in company identification, payment systems
• products analytics

were reporting to me. My department had 14 full time employees plus working students. I was a driving force behind the reshaping of analytical teams to accomodate shifting company requirements as Billie matured.
