Freelancer profile translated to English.

Description

My skills in Machine Learning and Computer Science allow me to manage complete data projects: from data acquisition, data cleaning and analysis to model design and performance evaluation.

I had the chance to work on various projects such as:

- Image classification (automotive)

- Fraud detection

- Recommendation system

- Text recognition

- Image processing

- Data visualization

I implement Machine Learning applications, regardless of the business sector, the type of data (image, text, raw data, etc.) and the type of task (prediction, recommendation, extraction, etc.).

I assist you from exploration to industrialization, including research and validation, and even data collection.

Do not hesitate to contact me, I will be happy to discuss your problem.
