• Creating intuitive dashboards for technical, operational and senior stakeholders
• Improving existing reporting processes and replacing manual reporting where appropriate
• Ensuring reporting is accurate, performant and appropriately governed
• Supporting data validation, reconciliation and quality activities
• Working alongside Data Engineers, Data Architects and migration specialists
• Producing clear documentation and supporting knowledge transfer

Strong experience across:

• Microsoft Power BI
• DAX
• Power Query/M
• SQL
• Data modelling and dashboard design
• Connecting Power BI to multiple data sources
• Building reporting solutions from complex datasets
• Translating stakeholder requirements into technical solutions
