About

14+ years of experience designing and delivering end-to-end planning solutions across Retail, CPG, and Pharma. I lead complex supply chain transformations, owning solution design, delivery outcomes, and long-term value across client portfolios. My work sits at the intersection of business strategy, data, and technology: translating complex supply chain problems into structured, scalable solutions. I’ve led multi-functional teams through high-stakes implementations, balancing architectural rigour with execution discipline. The focus is not just go-live, but ensuring decisions, processes, and systems hold up over time. I pay close attention to how choices compound across models, workflows, and teams. Strong outcomes come from clear ownership, thoughtful design, and consistent standards.
