Profile

Data Scientist with 3+ years of experience in consulting, specializing in end-to-end solutions using Python, PySpark and R - from data preparation to deployment of predictive models (regression, classification, and time series). Have worked on cross-sector projects, adapting analytical solutions to different business contexts. In my daily work, I use and study practical applications of LLMs for process optimization. Seeking opportunities as a Data Scientist or Machine Learning Engineer, with interest in both traditional modeling and innovative projects involving generative AI.
