Supply chain systems research

• Study Abroad Intercultural Learning Scholarship
• Researched supply chain systems, comparing operational practices between Spain and the U.S.
• Analyzed cross-cultural differences in workforce dynamics and their impact on efficiency and management approaches

• Developed an Excel-based tactical planning tool integrating demand forecasts, capacity requirements and operational constraints, enabling scenario analysis and more informed 18-month production decisions at Michelin's largest North American manufacturing plant.
• Evaluated production capacity, demand forecasts and resource limitations to identify supply risks, improve planning visibility and support proactive manufacturing allocation decisions.
• Collaborated with Supply Chain, Manufacturing and Operations teams to develop Power BI dashboards mapping end-to-end processes, identify production bottlenecks and drive improvements in plant performance.

Procurement & Inventory Management

• Managed daily inventory orders of $3,000–$9,000 using demand-based forecasting, optimizing stock levels, reducing waste and maintaining accurate product availability.
• Trained and onboarded more than 9 employees on standardized operating procedures and food safety protocols, improving process consistency and operational efficiency.
• Worked across 10+ back-of-house stations, supporting workflow optimization, bottleneck reduction and continuous operations in a fast-paced environment serving more than 150 customers per hour.

• Collaborated with a 6-member committee to plan and execute campus engagement initiatives that fostered inclusion and strengthened community connections, reaching 300+ students and staff.
• Independently organized and led select events, creating welcoming spaces that encouraged student participation and a stronger sense of belonging on campus.
• Mentored a first-year Supply Chain & Operations Management student, supporting a smoother transition into college and greater confidence navigating the program.

Team of 5 · demand forecasting and financial projection

An Excel-based tactical planning tool integrating demand forecasts, capacity requirements and operational constraints — enabling scenario analysis for 18-month production decisions at Michelin's largest North American plant — plus the Power BI dashboards the teams read it through.

Supply Chain Intern · built and delivered the tool

A process and wait-time study of store operations — flowcharts, process analysis and queuing theory applied to identify bottlenecks and recommend changes that increased throughput and improved service levels.
