• Led and grew a Data Science team, significantly lowering new hire ramp-up time, and consistently prioritized challenging, high-impact projects that directly led to multiple senior promotions within the team.
• Partnered with Data Eng to architect and operationalize the metrics and experimentation framework for Google Merchant Center.
• Collaborated with Eng and PM teams to architect novel holdback and ablation studies on Shopping features within Google Search, accurately assessing the short-term and long-term on user trust, query relevance, and retention within the Shopping ecosystem.
• Improved the org’s ability to attribute impact by established rigorous standards for causal inference, using quasi-experimental and observational methods (e.g., diff-in-diff, CausalImpact) to measure long-term impact in scenarios where randomized A/B testing was infeasible.
• Ensured best practices are followed and any double counting is avoided to fill in missing conversion data that was being generated via multi-touch-attribution so we don't expose any critical bugs in those approaches to our merchants.
• Designed the data science workflows on a large portfolio of feature launches with shopping ads and organic teams, contributing to all phases from opportunity sizing to experiment design to launch analysis.

• Led my team to define and implement success metrics for Play Store ranking and discovery features.
• Led the creation of an app quality model, generating a predictive score for every app and game on the Play Store using human-eval based ground truth data, which was integrated into ranking algorithms.
• Modeled the two-sided marketplace ecosystem, creating segmentation models that balanced developer supply with consumer demand.
