At Cigna, I build dbt data frameworks and dimensional models in Snowflake for healthcare reporting. This work improves data consistency and lineage across reporting domains.
I design and maintain Power BI semantic models and unified KPI frameworks for clinical operations. I’ve also built reusable reporting datasets and core metric definitions, reducing turnaround time for critical operational data requests by approximately 30%.
At Cigna, I implemented automated dbt data quality tests that identify schema drift and reduced downstream reporting errors by over 25%. I’ve also optimized Snowflake schemas and query strategies, reducing complex data retrieval times by nearly 30%.
Previously, at Orion Technolab, I developed SQL queries, Power BI dashboards, and DAX measures for financial reporting and KPI monitoring. I also built Tableau visualizations and reporting workflows that reduced manual spreadsheet processing time by nearly 40%.
