At Signet jewelers, I develop and test Python and SQL pipelines that move sales data from retail systems into the warehouse. I also manage Apache Airflow workflows for daily inventory processing.
I use Apache Spark and PySpark to transform transaction data for analytics, and design data models in Snowflake and Amazon Redshift for business intelligence. I’ve also supported Kafka and Spark workflows for real-time e-commerce data.
At Geisinger, I ingested healthcare data into an AWS S3 data lake and transformed medical records with PySpark on AWS EMR. I optimized Redshift queries for clinical reporting and configured Airflow workflows to deliver patient data for analysis.
At Ochsner Health Systems, I supported 19+ ETL applications and developed Python and Shell scripts that reduced manual processing effort by 40%. I also conducted root cause analysis for production issues and mentored junior staff on ETL practices.
