What I'm looking for

I am seeking a leadership role where I can optimize end-to-end supply chain operations, use data to reduce costs and risk, mentor teams, and deliver reliable logistics in regulated or high-precision environments.

I am a supply chain and logistics leader with 15+ years of experience improving freight operations across healthcare, retail, and technology-driven environments.

I specialize in demand planning, inventory optimization, and process improvement, and have driven measurable outcomes such as a 99.9% service level for critical finished goods, a 40% reduction in transportation delays, and a 90% improvement in inventory efficiency through nationwide tools and vendor negotiations. I build KPI dashboards, negotiate contracts, and collaborate with engineering, quality, manufacturing, logistics, and warehouse teams to ensure on-time delivery and compliance.

I also bring hands-on e-commerce and operations experience as a co-owner and CTO, where I cut fulfillment time by 40% and reduced operational costs by 25% through technology and vendor coordination. I lead cross-functional teams with a focus on operational excellence, data-driven decision making, and continuous improvement.
