About me
I build Power BI dashboards for every area of a company, with a strong specialty in purchasing, warehouse, inventory and maintenance control.
With 10 years in supply and maintenance operations and 2 years building dashboards, I know what a stock-out, a late purchase or an idle machine costs, so I build around those real decisions, not just charts.
Tools: Power BI, DAX, Power Query, SQL, Python and Excel.
Message me with your data and your goal, and I'll tell you the best way to approach it.
