- Pioneered a novel approach to evaluate Grammarly's referral program impact, overcoming traditional A/B testing limitations by integrating Propensity Score Matching (PSM) with an Artificial Counterfactual Estimation (ACE) model. This method involved matching users based on observable characteristics and engagement behaviors, then estimating the program's effect with a machine learning-based causal impact analysis. This strategy enabled a nuanced understanding of the program's effectiveness, tailored to diverse user segments and behaviors, significantly enhancing targeting and optimization efforts. - Conducted a comprehensive causal inference analysis to measure the incremental impact of launching GrammarlyGO, an AI writing assistant. Utilized Bayesian time series models to predict counterfactual scenarios and employed difference-in-differences estimation, coupled with Dynamic Time Warping, for precise control and treatment group comparisons. This approach provided pivotal insights into the AI assistant's effectiveness, guiding strategic decisions.- Designed a predictive machine learning model to forecast 4-week user retention based on initial user actions, employing XGBoost and Shapley values to identify key factors influencing retention. Implemented strategic product interventions that targeted these factors, significantly boosting user engagement and retention rates.- Engineered a subscription churn prediction model, leveraging a comprehensive dataset encompassing product engagement and user demographics to accurately forecast churn likelihood two months prior to renewal dates. This enabled the implementation of proactive retention strategies, significantly reducing churn rates and enhancing customer lifetime value.
