One thing I've learned in my career is that Power BI projects succeed when they start with understanding first - not dashboards. Before I build anything, I take time to understand the business, the people, and the decisions Power BI needs to support. That's how I create solutions that don't just look good - but drive real outcomes. Specialties: - Financial reporting: P&L statements, balance sheet, income statement, cash flow analysis, budgeting, forecasting, variance analysis - Operational analytics: Sales performance, KPI dashboards, YoY/QoQ/MoM comparisons, customer segmentation, retention, trend analysis - Technical expertise: Advanced DAX measures, Power Query transformations, Power Pivot, star schema design, time intelligence functions Why clients choose me: ✦ Business-first approach - 10+ years in finance, banking, and sales means I understand the decisions behind the data ✦ Technical + design excellence - Dashboards that perform well and look professional for any audience ✦ Independent execution - I work from a brief, ask the right questions, and deliver results with clear communication Need Power BI solutions that combine technical excellence with business understanding?
