Michael E.

Senior BI Developer / Analytics Engineer (Power BI + Tableau + SQL)

I build scalable Business Intelligence systems that leadership teams rely on. With 9+ years of experience across BI, data modeling, and data engineering, I help companies transform fragmented data into a clean, reliable source of truth — and turn it into executive-ready dashboards that drive real decisions. I don’t just build reports. I design the entire analytics foundation behind them.
