My approach to BI
Beyond pretty dashboards
Good BI isn't about pretty dashboards — it's about building scalable, maintainable systems that create real business value.
Efficiency by design
I focus on efficiency and automation in every solution — reducing manual effort, improving data reliability, and helping teams make faster, better decisions.
Grounded in utilities
Coming from the utilities sector, I understand data at scale — meter data, consumption patterns, regulatory reporting — and how to turn it into something teams can act on.
