Nubank - Running a Fintech on ML

Nubank is a Fintech providing credit and banking services to more than 20 million customers. Data science has been one of the company's pillars since the beginning, and many of their critical decisions in production are made with ML, in areas such as Credit, Fraud and Customer Service. We discussed how Nubank develops, deploys, and monitors ML models, and also talked about how they built those in-house solutions over the years. Today, Nubank uses MLOps to support a team of more than 70 Data Scientists/ML Engineers.
