About

I currently work at Amazon in Supply Chain Planning, operating at the intersection of demand, capacity, and execution across multiple European markets. My role focuses on translating demand signals into decisions that directly impact delivery performance, resource allocation, and operational efficiency at scale. I work closely with fulfillment centers, transport, and planning teams to align execution with network-level priorities, often managing trade-offs between speed, cost, and capacity. I have experience supporting high-volume operations (>1M units/day), improving forecast accuracy, and contributing to improvements in customer delivery speed during peak periods. I also build tools and automation to improve decision-making speed and scalability. More broadly, I’m interested in how operations, data, and supply dynamics drive business performance, and I’m particularly motivated to move closer to roles focused on growth, partnerships, and marketplace strategy. Outside of work, I care deeply about mental health awareness and sustainability, and believe that long-term business success should go hand in hand with positive impact on people and the environment.
