Data Scientist
CurrentAs a full stack data scientist my task is to deliver proactive fraud protection through artificial intelligence and machine learning, a key part of dLocal's Fraud Prevention Service for merchants. We develop multiple cross-industry machine learning models, leveraging big data to detect specific fraud patterns for every business model. Our Fraud Prevention solutions also include Network Analysis using complex graph connections, an essential tool for effectively preventing the most elusive fraud attacks. Our objective is to build a first-class Data Science framework by following best practices such as a CI/CD pipeline for machine learning models, an Online Feature store for swift model training and deployment, and continous model monitoring.Tool: Python (e.g., Pandas, Matplotlib, Seaborn, Scikit-learn, Keras, XGB), PySpark, AWS ( SageMaker, QuickSight, S3, Athena, EC2, Redshift), Git.
