Skills

Whether I'm automating a KPI report, stress-testing a financial model, or building dashboards for clients across three continents, my focus is always the same: turn messy, complex data into something a leadership team can actually act on — and Power BI, Tableau, Advanced Excel, and SQL are the tools I trust to do it.
