Data Analyst | Business Systems Analyst | Business Analyst — SQL · PowerBI · reporting

I turn large, messy datasets into decisions people can act on.

Roughly seven years turning business data into reports and dashboards that, not only show data, but help leaders take action. Lately I have been working on honing my SQL, PowerBI, and other analytics skills.

Selected work

Analyzing 2.7M U.S. flood-insurance claims with SQL

SQL Server · T-SQL · Power BI

About

I'm a data and reporting analyst with a background in business systems analysis. Most of my everyday work is SQL and PowerBI. I enjoy building the queries that pull the data together and the reports that make it legible to the people making the call. I've built SSRS reporting and PowerBI dashboards in a previous role, and I care most about being able to see my work make an impact.

I'm currently focused on roles in data analytics and business analysis in the Jacksonville, FL area or remote.
