I’m a Results-driven Senior Analyst with 6 years of experience leveraging advanced analytics and ML models to drive business growth and user engagement. I specialize in designing complex A/B testing frameworks and turning complex behavior data into actionable product strategies.
At HomeDepot, I designed and executed a multi-layered A/B testing framework, and engineered output schemas and computed metrics in BigQuery integrated into Tableau dashboards for real-time insights. I also lead 7+ personalization projects, synthesizing website, transaction, and engagement data into executive-ready deliverables.
Previously, I worked as a BI Specialist where I developed a predictive inventory model in Power BI and built automated data pipelines to reduce manual processing time. I’ve also supported enterprise clients and coordinated planning by collaborating with product teams and stakeholders, and I supervised 5+ analysts through training sessions as a Product Analyst Assistant Team Lead.
