What I'm looking for

I'm looking to build secure, scalable cloud data platforms and end-to-end pipelines, particularly in Azure or multi-cloud environments, where I can improve performance, reliability, data quality, and automation.

At Cigna HealthCare, I build enterprise ETL and ELT pipelines for healthcare and state government platforms, including programs for Georgia and New Mexico. I optimize PySpark pipelines in Azure Databricks for claims, eligibility, provider, and member data, improving processing performance by 30–35%.

I migrate Teradata and on-premises systems to Azure Data Lake and Azure Synapse Analytics, integrate Kafka for near-real-time ingestion, and build Python Azure Functions for validation, enrichment, and routing. My work has reduced data latency by approximately 40% and manual processing by 25%.

Previously at FIS Worldpay, I developed SQL and Python ETL pipelines for e-commerce transaction, customer, sales, and inventory data. I also built Spark and Kafka processing workflows, data models, validation checks, and Tableau reporting solutions.

I bring over 12 years of experience across Azure, AWS, Hadoop, Spark, SQL, and Python, with a focus on secure, reliable data platforms. I hold Azure Fundamentals and Databricks Data Engineer Associate certifications.
