ABOUT

I am a researcher and analytics practitioner with a foundation in psychology, and when I look at brand or research data, I start by asking, ย "What decision can this number help someone make?" I care less about listing metrics for their own sake and more about turning them into insight that helps real people act.

My strength is building an end-to-end flow from problem definition to research design, data design, modeling, and finally dashboards or reports. I design around how the output will actually be used, not just how it looks on paper.

More recently, I have been combining LLM and RAG approaches with work such as segmentation, demand forecasting, and campaign-effect analysis so the result is not just a report, but an AI-based service that can explain the context behind the answer.
