About Axel

A graduate of the École Normale Supérieure and a data scientist for 5 years, my various experiences in research and in small companies have given me a comprehensive view of how data utilization can impact businesses.

My specializations:
- Data analysis through statistical modeling (when necessary),
- Identification and understanding of Key Performance Indicators (KPIs),
- Implementation of recommendation algorithms, from prototyping to industrialization,
- Exploitation of text data using Natural Language Processing (NLP) algorithms,
- Creation of data visualizations and dynamic tracking dashboards,
- Implementation and exploitation of experiments (including A/B tests).

Furthermore, my projects have also allowed me to develop skills in:
- Retrieving data from other websites through scraping,
- Data routing by creating ETL (Extract-Transform-Load) processes,
- Data project management, from requirements gathering to industrialization, including prototyping and testing.

Naturally very pedagogical, I am capable of providing training in various areas:
- Data structuring,
- Data cleaning and visualization,
- A/B testing
- Understanding machine learning algorithms,
