What I'm looking for

I’m looking for a supply chain planning role where I can lead S&OP and forecasting, automate reporting with Python/SQL/Power BI, and improve service and cost across international markets in a cross-functional, fast-paced environment.

I’m an Industrial Engineer with 5+ years of experience in supply chain planning across demand, production and sourcing in FMCG and export operations. I specialize in improving forecast accuracy, reducing costs, and building data-driven solutions that make planning decisions faster and clearer.

In my current role as Sourcing Planner at Viña Concha y Toro, I lead supply planning for key export markets (UK, Nordics and China) and align demand, inventory and production decisions across international operations. I automated S&OP reporting using Python and Power BI, cutting weekly manual reporting from several hours to under 5 minutes, and I built an inventory coverage dashboard from scratch by integrating stock and sell-in data sources.

Previously, as Head of Supply Planning at Adelco, I led purchasing and supply planning across 1,200+ SKUs and reduced the portfolio by 36.5% while limiting sales impact to 15%. I’ve also developed statistical demand forecasts in Python across 10,000+ product-location combinations (improving accuracy from ~60% to ~80%), implemented S&OP, and designed an allocation optimization model to reduce stockouts and improve lost sales performance.
