Neemias Buceli Data Science Portfolio

Context

Welcome to my Data Science Portfolio. Here, I showcase the insights and skills I have acquired throughout my journey in the field. You’ll find a collection of case studies, research papers, and code that illustrate my work and expertise.

Note: I regularly update this repository with new projects and links to additional repositories for more complex projects that exceed the scope of this one. Stay tuned for more exciting updates!
