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.
