What I'm looking for

I'm looking to apply econometrics, machine learning, and Python to complex data problems involving forecasting, credit risk, and evidence-based decision-making.

I've built a Bayesian VAR macroeconomic stress-testing platform in Python, forecasting Argentine activity, inflation, monetary base, and FX-gap scenarios from public data.

I also developed a Home Credit default-risk pipeline using SQL, Pandas, XGBoost, Weight of Evidence binning, and Logistic Regression, achieving a ROC-AUC of 0.7240 while preserving leakage-free inference through out-of-fold stacking.

As a final-year Economics student at Universidad Nacional de Tucumán, I bring econometrics, time-series analysis, hypothesis testing, and independent research experience to data science problems.
