Summary
👤
Senior🎓
Top SchoolJoão A is a Data Science Specialist II with eight years of experience applying mathematics, optimization and statistical modeling to real-world problems at Porto Seguro’s R&D cell. He designs and deploys ML solutions across fraud detection, image classification, recommendation systems, geospatial analytics and insurance risk, with hands-on experience in MLOps and operational research. Trained in applied mathematics and optimization (ICMC-USP), he bridges academic methods and production engineering to bring state-of-the-art AI into operations. Notably, his early research on inverse Poisson problems and mathematical models of natural forms reflects a deep theoretical background he leverages for practical, computationally efficient solutions. Based in São Paulo, he is driven by elegant, theory-informed approaches to messy industrial data challenges.
