Data Analyst (Power BI)

Power BI Tableau Dimensional modeling SQL

Context

At Altia I worked as a data analyst, focused on migrating existing dashboards from Tableau to Power BI.

What I did

I migrated full dashboards between platforms, built dimensional data models and optimized visualizations so information stayed readable and actionable for business users. I worked directly with clients to translate business needs into dimensional models and visualizations useful for decision-making.

Relevance today

I apply this same data modeling judgment in database design at both Nattia and LIT.
