About João

I help organizations turn complex data into clear, reliable insights through end-to-end Power BI solutions and Microsoft Fabric architecture.

With 7+ years of experience, I specialize in building scalable dashboards, optimizing DAX and data models, and connecting Power BI to modern data platforms — including Fabric Lakehouse, Dataflows Gen2, Snowflake, and Databricks. I'm also experienced in BI platform migrations, data governance, and RLS implementation.

I work across industries and functions — from Finance and Sales to Operations and Marketing — and communicate fluently with both technical teams and business stakeholders in English and Portuguese.

Typical projects: Power BI development & optimization, Microsoft Fabric architecture, dashboard migrations, KPI frameworks, data pipeline integration, and ongoing BI support.
