I have extensive experience within large Parisian Telecom companies with the first generation of data analysis tools.
I embraced the latest data analysis technologies to provide services even closer to business needs.
Now, I support my clients from the Pays de la Loire region with their technical and organizational needs.
I don't have ready-made plans, but rather an approach of listening to respond exactly to your needs.
My strengths:
- 📈 Data Analyst and Power BI/DAX Trainer. (Companies M2I, ENI, Kiluz). With Power BI, you have a powerful and efficient tool that I will customize according to your needs. As the graphical interface of Power BI is easy to use, you will be able to easily update your tools.
- 📲 Expert in Excel and PowerQuery for fast and efficient data integration. The Excel/PowerQuery tandem works very effectively to allow you to integrate and manage your data with brilliance.
- 📲 Specialist in Microsoft's Fabric environment for efficient and secure enterprise BI management. Microsoft's Cloud is the most efficient on the market and is compatible with all cloud storage.
- 📚Specialist in text indexing via data models. (this technology will allow you to speed up searches on your document base and the associated website).
- 👨🎓 Business Intelligence Trainer in various schools. I leverage my experience to provide effective and easily actionable training in companies.
