European Union·E-commerce

BigQuery + ML for a European jewellery retailer.

The problem

Reporting lived in disconnected silos; the team couldn't tie ad spend to lifetime value or predict repeat purchases.

  • Unified spend + revenue + LTV dataset
  • Repeat-purchase propensity model
  • Looker Studio executive reporting
