What I'm looking for

I'm looking to build reliable, governed data solutions and dashboards, partner closely with stakeholders, and improve reporting through data migration, automation, and analytics.

At Ally Financial, I modernized a key executive report by migrating its data source to Snowflake, developing the SQL dataset, and building a Power BI dashboard that reduced runtime by 40%.

I establish data quality and reconciliation controls for legacy-to-Snowflake migrations, helping stakeholders rely on accurate reporting and decision-making. I also translate reporting needs into tailored SQL datasets and Power BI reports, refining outputs through stakeholder feedback.

Previously at Jobcase, I built Tableau dashboards for paid channel performance, reducing manual reporting by about five hours per week. I also automated event fulfillment with SQL, eliminating more than two hours of daily manual validation work.

My analytics foundation includes a healthcare pricing capstone using data from 120 Michigan hospitals, where I analyzed predictors in Python and created an interactive Tableau comparison tool.
