Materials Team Manager with experience leading customer-facing materials operations and cross-functional alignment between Procurement, Planning, and Manufacturing in complex, regulated environments. In this role, I was accountable for demand and supply stability, inventory health, and service performance, acting as the primary interface between internal teams and customers. I led the analysis of customer forecasts received through portals, validated capacity and lead-time feasibility, and ensured executable plans were integrated into operational and forecasting cycles.
