What I'm looking for

I'm looking to build reliable, scalable cloud data platforms and ETL/ELT pipelines that improve analytics, reporting, data quality, and business decision-making.

I've built payment, supply chain, and analytics data platforms for TransUnion, Guidehouse, AGS Health, and Scio Management Solutions. At TransUnion, I designed ETL/ELT pipelines and Snowflake and Amazon Redshift warehouse structures for enterprise reporting, using PySpark, Databricks, Python, AWS Glue, and Amazon S3.

I've also developed Azure-based payment-data workflows with Azure Data Factory, Azure Databricks, Synapse Analytics, and ADLS Gen2, creating curated datasets, reconciliation processes, and data quality checks. I focus on reliable ingestion, transformation, validation, performance tuning, and automated reporting with SQL, Python, Power BI, and cloud data platforms.
