At PayPal, I engineered Bronze–Silver–Gold lakehouse pipelines for payment data using Azure Databricks, Delta Lake, Auto Loader, DLT, Kafka, and Spark Structured Streaming. This work improved payment-domain data availability by 40%.
I also optimized Spark execution plans, partitioning, caching, and Delta Lake files, reducing processing costs by 22% and critical-job runtime by 35%. I implemented validation, reconciliation, lineage, access controls, and observability across curated datasets.
At WPP, I designed parameterized ingestion pipelines for 15 enterprise systems and improved cross-system reconciliation accuracy to 99%. I delivered dimensional datasets to reporting teams, reducing manual Power BI preparation by 12 hours per week.
Across roles at Amazon, iTalent Plus, and Systems, I worked on AWS, Snowflake, and GCP data platforms, as well as Spark and Kafka pipelines. My healthcare data engineering work included HL7/FHIR ingestion design and secure handling patterns for sensitive patient data.
