About Léa

My professional experience has focused on data support for various topics, whether in performance management, data process structuring, or the implementation and analysis of monitoring indicators. I work across the entire project chain, from understanding the context to developing recommendations. I typically work manually with tools like Excel or SQL (to optimize the adaptability of monitoring), but also with BI solutions like Tableau.

Therefore, I am an autonomous and versatile individual who enjoys developing projects. I have worked in companies of different sizes and in various departments ranging from marketing to data, including e-commerce. I have thus seen different structures, challenges, and use cases. All of this makes me very versatile and gives me a great capacity for adaptation, allowing me to be operational quickly. My greatest strengths are a strong team spirit and high adaptability: I communicate easily and have a constant need to resolve conflicts and provide solutions.

My developed skills include:

Project Management: context understanding, problem definition, roadmap definition and monitoring, recommendations

Change Management: support and training in internal tool changes for various users, workshop organization

Data Analysis: monitoring marketing campaign performance, customer behavior analysis, epidemiological monitoring analysis

Data Visualization: with BI tools like Metabase and Tableau Software, but also custom productions in R/SQL/Excel. Collaborative work on Gitlab
