About Youssef

Hello,

A Data Scientist specialized in Data Science and Machine Learning, capable of conducting data analyses and creating tools that enable better decision-making. I aim to bring my expertise to support you with your data analysis challenges.

I am convinced that the synergy between business knowledge and technical skills is the key to the success of a data science project. For this reason, I place communication at the heart of my work.

My expertise:

- Data Science: creation of predictive models such as regression/classification/clustering/recommendation systems/text mining/NLP/OCR
- Functional analysis: understanding and formalizing needs in clear and concise language
- Data: extraction, formatting, exploitation of data

My main work tools:
- Dataiku for integration/preparation/visualization/Machine Learning models/production deployment
- Python with Scikit Learn libraries for predictive Machine Learning algorithms, Pandas for data extraction/exploitation, Matplotlib & Seaborn for visualization.
- SQL language for querying your databases
- Tableau Software for data graphical visualization
- GCP for cloud
I will assist you from exploration to industrialization, including research and validation, and even data collection.
I would be pleased to discuss your challenges with you.
