• Partner with commercial teams to deliver insight into pricing, promotions, customer behaviour, and revenue performance.
• Define, standardise, and monitor KPIs across sales, marketing, product, and customer domains.
• Drive automation and self‑service BI, reducing manual reporting through Power BI, Power Apps, and workflow automation.
