From messy data to ready to use results

À propos de moi
I’m a Data Scientist & Analyst with a Master’s in Statistical Engineering and experience delivering end‑to‑end data solutions.
I worked on France’s national health database (SNDS), building fraud‑detection pipelines that improved F1‑Score by +15% and identified €500k+ in fraud.
As a freelancer, I processed a 5M‑row, 12‑file health dataset (~2.4 GB) in one day — cleaned, merged, validated, and delivered ready‑to‑use.
I focus on clean, documented, reproducible work: structured datasets, predictive models, automated pipelines, or Streamlit apps — built for clarity and impact.
