Accomplishments

  • Led a full rebuild of the subscription lifecycle model, replacing daily full-table rebuilds and premature aggregation with an event-driven, user-journey-based “Uber” model that tracks each subscriber’s complete lifecycle across trials, promos, engagement, pauses, cancellations, and churn.
  • Re-architected consumption analytics from the ground up, replacing a poorly modeled, multi-fact design with a clean star schema; created an upstream layer to reduce Google Analytics processing from 16TB/day to ~4GB/day using incremental logic instead of full rebuilds.
  • Integrated AI-assisted text classification into data pipelines to normalize and enrich messy sports metadata (e.g., team names, home/away indicators), improving data usability and downstream reporting accuracy.
  • Unified DTC and Amazon consumption data into a single conformed fact table, enforcing ID-based joins, separating facts from dimensions, and leveraging Power BI semantic modeling best practices to significantly improve performance, correctness, and maintainability.
  • Enabled true customer journey and churn attribution analysis, allowing stakeholders to trace individual user behavior end-to-end and understand why users convert, engage, pause, or churn — not just top-line counts.
  • Built 'Winback' data model and Power BI Report for stakeholders to analyze effectiveness of campaigns shipped to churned users.
