What I'm looking for

I'm looking to build scalable analytics solutions, define meaningful metrics, automate reporting workflows, and partner cross-functionally to turn complex data into strategic business decisions.

At HCA Healthcare, I transform complex datasets into actionable reporting solutions using SQL, dbt, Power BI, Python, and Redash. My work improved reporting accuracy by 35%, increased report adoption by 40%, and reduced dashboard refresh times by 50%.

I've delivered analytics across HCA Healthcare, JP Morgan Chase & Co., and Elevance Health, working with millions of transactional records, operational metrics, and cross-functional teams. I build interactive dashboards, automate reporting and validation workflows, optimize Redshift and PostgreSQL queries, and investigate data-quality issues through root cause analysis.

I use modern analytics platforms including AWS, Azure Data Factory, Azure Synapse Analytics, Tableau, Looker, and dbt, along with ChatGPT and Claude to accelerate documentation, debugging, and query optimization.
