About

I'm a data scientist with a background in computer science, a postgraduate degree in machine learning and AI, and an AWS certification. I've led end-to-end machine learning projects across industries—from industrial automation and computer vision to real estate analytics and legal operations. My experience includes companies like Apodi, Dell Lead, Kenlo, Compass UOL (Informa Markets), and Petrobras. I specialize in building scalable solutions using Python and AWS, with a strong focus on cost-efficient deployment via AWS Lambda. My work has ranged from optimizing cement production and evaluating employee performance to predicting property prices, assessing credit risk, scoring sales leads, and estimating legal workloads. I consistently apply data-driven strategies to improve efficiency, reduce costs, and drive smarter decision-making.
