About

I'm a Senior Business Data / Analyst with over a decade of experience delivering automation, financial analytics, and enterprise dashboards across Fortune 500 organizations — Liberty Mutual, Cruise, EY, Accenture, and General Motors.

I specialize in translating complex business problems into clean data solutions: ETL pipelines, Power BI dashboards, Python automation, and SQL data models that drive real decisions at the executive level. My domain runs deep in finance and operations — I understand what the business actually needs, not just what it asks for.

I'm now focused on a deliberate transition into Cloud Engineering on AWS, working through the certification path (CLF-C02 → SAA-C03 → DEA-C01) and applying my infrastructure instincts from years of building data pipelines at scale. My background in Azure App Services, BigQuery, and Snowflake gives me a strong foundation to build on.
