I don't just report data | I find the "hidden money" in your marketing funnel.

Conversion Path Audits: Custom Sankey diagrams to find friction points.
Performance Marketing: Attribution modeling and ROAS/CAC analysis.
Data Engineering: Automating raw data flows from BigQuery to your dashboard.
Strategic Insight: I don't just show you what happened; I show you the $30M+ opportunity gaps you're missing.
