About Me

With 7 years of experience applying machine learning in industry and academia, I offer my services to help design, implement and scale up data driven projects. I am mostly loacted in Paris or Tokyo and usually open to propositions around the world in French, English or Japanese.

Recommendation for online shopping, Sentiment Analysis of products reviews or deployement of a distributed data processing architecture using Spark are examples of projects I can assist you in implementing successfully. I can help you solve problems that may occur at each step of the process from conception to implementation to deployment in production.

I am expert in

Mathematical Modeling

I can help you perform exploratory analysis on your dataset, choose the right model among traditional machine learning algorithms or provide custom modeling solution to the task at hand.

Software Development

As an experienced software engineer I strive to implement solutions that are scalable and easy to maintain. I produce tested and documented code that is evolutive and easy to deploy.

Natural Language Processing

Sentiment analysis, Named Entity Recognition, Topic Modeling. Statistical analysis and modeling of textual data is one of my favorite domain of application. I can perform text processing in French, English or Japanese.
