Internship

Data Scientist @ Klesia

Jul 2023 — Dec 2023 · Montreuil, Île-de-France, France

Worked with the data science department on a research-oriented machine learning project for detecting company insurance payment anomalies in DSN data and improving an existing non-ML anomaly detection approach.

What I did

  • Learned and used SAS Enterprise Guide to understand and query Klesia databases.
  • Created datasets from raw, uncleaned internal data using SAS Enterprise Guide and Python.
  • Designed feature engineering and embedding approaches for company-level anomaly detection.
  • Built a PyTorch neural network trained and evaluated through Azure ML to detect DSN anomalies.
