👋 Hi, I'm Sandra

A financial crimes leader passionate about using data and tehcnology to protect both people and businesses.

🛡️ What I Do

For me, fraud prevention is about more than just rules and analytics—it's about trust, customer experience, and reducing harm. I use this space to share the technical side of my work.

  • SQL: For KRI/KPI tracking and deep-dive loss analysis.
  • Python: To build automation for chargeback workflows.
  • Tools: Databricks, Snowflake, Panther, SQLServer, Tableau.

📊 GitHub Portfolio

I'm using GitHub to demonstrate the technical skills that support my strategic work. Check out my repositories to see examples of:

  • Identifying Financial Crimes Red Flags in Data
  • Fraud Operations & Investigator Productivity
  • Loss Forecasting & Reporting
