My work sits at the boundary between data and strategy — between what a model says and what a room decides.
I started in data science at Publicis Sapient: 25 months of building analytics pipelines for stakeholders who had more data than they knew what to do with. The lesson that stayed with me: the gap between insight and decision is a strategy problem, not a math problem.
