    paper Data Analyst

    I have built this project by leveraging the Advanced Excel Power Stack to transform over thousands of raw transactions into a high-performance executive engine. My design philosophy for this dashboard was to bridge the gap between complex data modeling and intuitive user experience.

    I have used Power Query to connect to raw data sources, ensuring all cleaning, column mapping, and data normalization happen automatically.

    I utilized Power Pivot to create a star-schema model, allowing me to link customer profiles, product SKUs, and sales logs. This foundation enables the dashboard to perform cross-table analysis that standard spreadsheets cannot handle.

    Designing for “Clarity at a Glance”: I structured the layout with an Executive KPI Ribbon at the top for immediate vitals, followed by trend analysis and operational splits. I used a cohesive color palette and clear spatial hierarchy to ensure the most important insights.
