I worked on a Power BI project where I transformed raw business data into interactive, visually engaging dashboards to support data-driven decision-making. The project involved connecting multiple data sources, cleaning and transforming data using Power Query, and creating calculated measures with DAX for advanced analytics. I designed custom dashboards and reports with charts, KPIs, and slicers, ensuring clarity and ease of use for stakeholders. The dashboards were fully branded, applying the company’s colors, typography, and styling for a professional look. Finally, I published the reports to Power BI Service, enabling team-wide access and collaboration, with role-based security to maintain data confidentiality. This project helped the business track key metrics, monitor trends, and make informed decisions quickly and effectively.
