What I'm looking for

Seeking a long-term opportunity in Procurement, Category Management, or Strategic Buying, leveraging my expertise in supplier negotiations, commercial conditions, forecasting, and cost optimization. Open to 100% remote, hybrid, or on-site opportunities based in Querétaro, Mexico.

I've led commercial category and procurement strategies at Avolta, Costco Wholesale, RadioShack, Shopee, and Gaon Innovación, managing national and international suppliers, P&Ls, pricing, contracts, and sourcing across consumer goods, retail, and manufacturing.

At Avolta, I led CAPEX procurement and implementation for three Turin ChocoBoutiques at AICM Airport, helping increase monthly Duty Paid food sales by 10%. Across my career, I've delivered cost reductions, launched new brands and products, increased category margins and sales, and managed supplier performance through strategic sourcing, RFQs, negotiations, sales forecast and cross-functional execution.
