I build scalable Azure data pipelines for analytics, risk, and business decisions.

At Zurich Insurance, I build Databricks and PySpark pipelines that process high-volume data for actuarial and risk models. I also design reverse ETL workflows from Power BI semantic models into Azure Data Lake and Databricks.

I've delivered Azure-based data warehouses, ETL pipelines, and Medallion Architecture implementations for Zurich Insurance, Baufest, bSide, Softtek, and Mexico's federal government. My work spans Azure Synapse Analytics, Snowflake, dbt, Azure Data Factory, Delta Lake, SQL Server, and Power BI.

I enjoy turning complex data into reliable business assets through traceable pipelines, data quality controls, performant models, and reproducible CI/CD deployments.
