At Integris Health, I build production AWS data infrastructure for clinical, claims, and operational analytics. I architected Kafka and Kinesis streaming with Databricks and PySpark pipelines on AWS EMR processing millions of healthcare events daily.

I design Bronze/Silver/Gold data layers, CDC ingestion, schema evolution, data quality validation, and Snowflake dimensional models. My warehouse optimizations reduced dashboard query times from 45–60 seconds to 3–5 seconds and cut compute costs by approximately 30%.

Previously at Humana, I built ETL/ELT and real-time streaming pipelines ingesting tens of millions of records daily, using Python, PySpark, AWS Glue, Kafka, Flink, and Kinesis. I also developed REST API integrations, addressed production streaming issues, and mentored junior engineers on distributed pipeline design.

My earlier work at Chickasaw Telecom combined Python, SQL, Azure Data Factory, Databricks, Power BI, and Tableau for operational reporting. I’m also building expertise in Microsoft Fabric and using agentic workflows to automate pipeline scaffolding, data-quality diagnostics, and documentation.
