À propos de moi
I hold a PhD in Statistics and over 10 years of experience in the private sector and academia.
I apply machine learning, deep learning, and econometrics to build robust models that inform decision-making. I value clarity, and you can expect transparent methods, clean code, and visuals—Matplotlib, Seaborn,
ggplot2, or Tableau—that explain the reasoning behind my model recommendations.
If you need reliable forecasts you can present with confidence, I can help.
