What I'm looking for

I'm looking for environments where I can apply and continue improving my knowledge in programming, machine learning techniques, and deep learning.

At CRESA S.A., I created R and SQL scripts for data cleaning, extraction, transformation, and analysis, and developed Power BI dashboards to support decisions on planting and harvesting, stockouts, and credit risk. I also analyzed credit scoring models for predicting defaulting customers.

At Université Gustave Eiffel, I explored theoretical properties of a softmax approximation to the bottleneck distance and implemented the formulation in Python using fractional linear models. My work also includes data analysis and cleaning, support for linear integer programming models, and web scraping.
