At Amazon, I analyzed and validated 10M+ records across 5+ source systems to support 20+ business KPIs and Power BI dashboards. I used SQL for data validation, reconciliation, and investigation of data discrepancies.
On my Real-Time E-Commerce Streaming Pipeline project, I published JSON events to Azure Event Hubs and processed them with Spark Structured Streaming in Databricks. I also implemented PySpark data transformations and a Delta Lake Bronze-Silver-Gold architecture.
