What I'm looking for

I'm looking to apply automation, analytics, and programming to improve business processes, data reliability, and decision-making while continuing to grow in artificial intelligence and business intelligence.

At Santander, I built Power Query pipelines for multi-currency reconciliation that reduced processing from two hours to under 10 minutes while removing manual data-entry errors. I manage foreign-currency liquidity, support international payments and collections, and resolve urgent discrepancies using SWIFT messages and daily currency-flow analysis.

Previously at GE Aerospace, I automated data extraction with VBA, built a Visual Studio and SQL data platform, and developed dashboards supporting manufacturing data and supplier process improvements. My mechanical and aerospace engineering background, structural simulation experience, and ongoing Master’s in Artificial Intelligence strengthen the analytical rigor I bring to automation and business intelligence.
