Freelancer profile translated to English.

Description

I process data in Python end-to-end: data analysis, data science, machine learning, AI, but also pipelines, ETL, visualizations, and application development.

A transversal profile (pure mathematics, philosophy, political science, economics), I know how to frame problems methodologically, bring conceptual solidity, analyze an existing situation, and communicate with the business.

As a VBA expert, I can analyze existing Excel/VBA/Access systems and convert heterogeneous data flows into reliable and automated Python systems.
