🤓More Details:

Power Apps:I design custom business applications using Power Apps to automate your internal processes. These Power Apps, integrated into your Microsoft environment, allow your teams to consult, modify, or enter data with ease. Data is hosted on Microsoft SharePoint and secured. I also integrate Power Automate to trigger automated workflows, alerts, or notifications as soon as an action is performed in Power Apps, enhancing automation and productivity.

Power BI (Tableau, or Qlik):I bring your data to life with Power BI and Tableau. Design of dynamic dashboards, report automation, KPI visualization, real-time monitoring: Power BI becomes your best ally for managing your performance. I leverage the full potential of Power BI within a Microsoft environment to simplify your monthly reporting and enhance decision-making.

Excel & Power Query:I use Excel and Power Query to automate your files (formulas, macros, PivotTables, charts), consolidate your multi-source data, and structure your analyses. Combined with Power BI or integrated into Power Automate flows, Excel becomes a powerful tool for the digital transformation of your business processes.
