I help companies understand their customers through data and behavioral science.
I combine behavioral science, NLP, and data analysis to extract actionable insights from customer feedback at scale. I've built systems that analyze thousands of customer reviews to detect emerging product risks, designed churn prediction models identifying at-risk customers 3 months in advance, and created automated sentiment analysis pipelines that turn messy qualitative data into clear business strategy.
What I deliver: Customer sentiment analysis | Churn prediction models | LLM-powered feedback analysis | Behavioral segmentation | Purchase pattern analysis | Voice of Customer (VoC) programs
Recent work: Built early warning system analyzing 1,000+ consumer health product reviews to detect safety issues before they became PR crises. Designed customer lifetime value optimization model tracking behavior across 7 segments, identifying 12% efficiency opportunity. Increased audience engagement 40% through data-driven behavioral segmentation.
