About
Short profile & context

I work at the intersection of Business Intelligence, KPI logic, and performance analytics. After a long career in project and operations roles, I transitioned fully into BI to help organisations make more confident, data-driven decisions through clear performance insights.

At Airbus (Operations), I support leadership teams by analyzing performance KPIs and designing performance views and reporting that highlight trends, risks, and priorities. My work focuses on performance interpretation and decision support, ensuring that data is clearly structured and meaningful for decision-making.

I’m particularly interested in how financial metrics and operational behaviour shape performance - especially in areas such as revenue, customer value, and risk. I enjoy BI work that combines dashboard ownership, analytical depth and clear performance insights with real business impact.
