Data Scientist with 13+ years of experience (SAS | R | SQL | Python)

I've been working with teams and projects related to Analytics, Data Science, Data Mining and Machine Learning for over 13 years, having helped dozens of people and companies to become more data-driven. For the last 5 years I've been working in the Financial Services industry, with topics such as Credit Risk, Credit Limits, Risk Modelling and Affordability Assessment. I own a Bachelor degree in Statistics and a post-graduate degree in Finance, being a former president of the Regional Council of Statistics in Brazil. I have also worked as a Data Science professor and have helped multiple researchers in the quantitative analysis of their papers and projects.

Sicoob is the largest Credit Union System in Brazil, having more than 6 million customers and over 20 billion dollars in credit portfolio. As a Risk Modeling Manager, I was responsible for managing the team's activities (18 data scientists), both from a technical and a business perspective. The team was in charge of developing and monitoring predictive models for Credit Risk (PD, LGD, EAD), Fraud Prevention and Anti-Money Laundering, as well as conducting statistical data analysis for the entire System. My duties also included reporting to the Executive Committee, in addition to negotiating and prioritizing demands with the IT teams and other business units. This paper shows how we used SAS to change Sicoob’s credit process as well as the main impacts (presented in Dallas-USA, at SAS Global Forum 2019): https://support.sas.com/resources/papers/proceedings19/3952-2019.pdf.
