Hi! I’m João Gabriel, a data scientist based in São Paulo, Brazil, with a strong passion for problem-solving and a keen interest in leveraging data to drive impactful decisions.
I hold a bachelor’s degree in Mathematics from the State University of São Paulo and a master’s degree in Mathematics from the State University of Campinas, where I specialized in Algebraic Number Theory.
In my current role as a data scientist, I use R, Python, SQL and Julia for data manipulation, statistical modeling, and automated reporting with Quarto. I work with machine learning using scikit-learn and tidymodels for model development and evaluation, and have experience in computer vision with YOLO and OpenCV. I also develop interactive web applications with Shiny, focusing on data visualization dashboards and platforms for monitoring models in production, as well as cloud-based automation and deployment using AWS (SageMaker, EC2, ECS, Bedrock, S3, rekognition).
