At MercadoLibre, I developed and orchestrated ETL pipelines and BigQuery jobs supporting moderation of around 400 million LATAM catalog items. I modeled and quality-checked tables in Data Mesh, and built KPI dashboards for contact rate and rollback rate. I automated daily monitoring and alerts for deviations, analyzed root causes and anomalies, and measured the impact of machine learning models. I detected a failure across three systems that generated contacts and identified around 200,000 top-selling items that were miscategorized. I coordinated improvements with Business, Tech, and customer service, and supported an end-to-end rollout across four countries covering around 15 million miscategorized items. Earlier, I researched logistics for small tea producers in Misiones and served as a teaching assistant for production planning and control courses at UNaM.
