Business Data Analyst - Turning complexity into clarity

Brussels, Brussels Region, Belgium

About

I'm a Business Data Analyst with over a decade of hands-on sales leadership experience, specializing in building Power BI reporting solutions that help organizations turn their data into clear, actionable insights. I bridge the gap between sales operations and analytics by designing tools that teams actually use to manage performance and drive revenue. ---What I do--- • Design and maintain Power BI dashboards and reports that make KPIs, sales performance, and budget tracking easy to understand and act on • Build and optimize data models using Power Query, DAX, and relational structures so reporting is accurate, scalable, and efficient • Integrate and transform data from multiple sources (Excel, SQL, legacy BI tools, and other systems) to create a single, reliable source of truth for stakeholders • Translate complex analysis into clear business recommendations, adapting the message for sales leaders, management, and non-technical teams ---My unique perspective--- • With more than 13 years as a Senior Sales Manager , I understand the realities of quotas, margins, and client relationships from the inside. • That experience guides the way I design Power BI solutions: every report, measure, and visualization is built to support concrete decisions, not just to look good. ---My foundation--- • I strengthened my technical base through intensive data analytics training and multiple projects involving Power BI, Python, SQL, and modern BI practices. • I earned a Dataiku Core Designer certification, which complements my BI skill set when working on more advanced data workflows or analytics use cases. • My core focus remains building practical, impactful Power BI solutions for business users.
