What I'm looking for

I am looking for opportunities that allow me to leverage my data science skills in innovative projects, ideally within a collaborative and growth-oriented environment.

I am a Data Scientist and AI Engineer with practical experience in predictive modeling, LLM-based automation, and operational optimization in both industrial and public data environments. My proficiency in Python, time series forecasting, cost analysis, and data visualization has enabled me to deliver high-impact results, such as reducing idle inventory by R$4.2M and automating classification for over 1.2 million documents using generative AI.

Currently, I work as a Performance Analyst at Sylvamo, where I led the development of an MRO Inventory Recommender that significantly reduced idle stock across multiple mills. My experience includes developing a time series forecasting system to support procurement strategies and designing Monte Carlo simulations for financial risk assessments. I have also collaborated with backend developers to create responsive web interfaces and integrate APIs, ensuring best practices in digital accessibility.

In addition to my technical skills, I have a strong commitment to community engagement, having founded MogiOpenData, where I built open data platforms to enhance transparency for local NGOs. My educational background includes a Bachelor's Degree in Chemical Engineering, complemented by an exchange program in the same field, which has equipped me with a solid foundation in both engineering principles and data science.
