About Greg

Data scientist/analyst for 8 years, I have acquired significant experience in banking and finance, although I remain open to exploring other sectors. My expertise primarily revolves around report generation and monthly closing programs, but I have also worked on predictive models and participated in process redesign. These missions aimed to optimize time, reduce manual tasks, and strengthen data reliability.

I have mainly used SAS and SQL, but I also have solid experience with Python, R, as well as platforms such as Dataiku and Alteryx. Learning to master new technologies or languages is a challenge I gladly welcome, with the goal of becoming operational as quickly as possible.

For me, knowing your data well is not limited to a technical mastery of databases; understanding the business meaning is just as essential. This allows for a better grasp of data-related interactions, more relevant report or model generation, and the delivery of real added value. Interaction with data-requesting teams is therefore paramount in my eyes.

Finally, I believe that a pleasant and collaborative work environment is not only enjoyable but also beneficial for efficiency. With a positive, generous, supportive, and cheerful nature, I always strive to improve the work atmosphere while remaining focused on achieving objectives and the efficiency of my mission.
