About Corentin

Coming from preparatory classes and an engineering school, I have a solid analytical culture and a real passion for data. I work daily on Excel, VBA, and Power Query to automate tasks, structure information, and analyze data effectively. I enjoy transforming complex files into simple, fast, and reliable tools. My goal is to make your numbers speak, save you time, and give you a clear vision to make decisions faster and better.
