Thierry in a few words

Plus de 7 ans d’expérience dans le domaine de la data, à la fois sur des sujets R&D et sur des problématiques business. J’ai travaillé au plus proche de la direction, des équipes tech et back-end, produit et métier.

J’ai réalisé des projets data de bout-en-bout, de la définition du problème avec le métier jusqu’à l’industrialisation d’algorithmes et leur suivi en production. Quelques exemples de sujets sur lesquels j'ai travaillé :
- catégorisation de transactions financières
- étude et mise en place de nouvelles stratégies de pricing
- scoring pour le moteur de recherche d’une marketplace
- segmentation client
- réduction de churn

Je pourrai vous aider aux niveaux stratégique et opérationnel, de la définition d’une stratégie data jusqu’à l’analyse et au développement de solutions techniques.

Thierry performed several missions at Qonto regarding data topics. He revamped large parts of our analytics. The latter involved analysing the need, designing the solution and shipping it as well as driving the whole project. Thierry is proficient in SQL and python as both a data scientist and a software engineer. He demonstrated great autonomy and professionalism which were critical to meeting deadlines for the projects.

Nizar Malkiya - Roland Berger


Thierry is a skilled Data Scientist capable of modelling, and analysing complex real world problems, and implementing Machine Learning models in different languages ( R, Python, C#...) under very strict time constraints. His great communication skills make him a valuable asset in team work, and while explaining technical results to a non-technical audience.

Emmanuel Costa - Bankin'


Thierry has worked with me here at Bankin' for 2 years. He occupied the position of Data Scientist and was totally autonomous in his tasks. He quickly became one of our most valued employees, the person everyone went to with questions and special projects. His dedication and willingness to data projects made Bankin' progress as never before. In his time at Bankin, he has shown that he has the technical, organization, and interpersonal skills that make a truly exceptional Data Scientist. In particular, if you’re seeking someone with a real rigor, as well as the ability to get up to speed quickly, Thierry offers all these skills, plus adaptability. We will miss having Thierry on our team, but our loss can be your gain. Please don’t hesitate to contact me with any questions.

Marc Lebel - LouerAgile


Working with Thierry was for me a great experience. He's a fast learner, has strong mathematical background, good at programming, and above all he has very effective communication skills. These allow him to collect meaningful data to make the right analysis and take good decision about your business.
