What I'm looking for

I'm driven by challenges where data can improve performance, optimize processes, and create measurable business impact.

At Cielo, I develop Supply Chain and Logistics analytics for the Control Tower, turning operational data and business rules into KPIs, dashboards, and insights for operational and executive decisions. I build SQL-based data processes and Power Automate workflows, and use statistical analysis to flag demand patterns and operational anomalies.

At Karcher, I worked across Sales, Market Intelligence, and Digital Marketing, creating Power BI reporting and automating market intelligence analysis with Python and Nubimetrics. That analysis identified a market opportunity that contributed to market share growth from approximately 2% to 20% in three months.
