What I'm looking for

I seek a role that fosters collaboration, innovation, and opportunities for growth.

I am a dedicated Data Analyst with a strong background in analyzing clinical datasets and enhancing reporting accuracy. Currently, I work at Providence Health Plan, where I have successfully improved resource planning accuracy by 25% through the use of SQL and Tableau. My experience includes automating data workflows using AWS Lambda, which has saved my team over two hours each week, allowing us to focus on strategic analysis and decision-making.

Previously, I served as a Data Engineer at Mattel, where I integrated over a million records using GCP BigQuery, significantly improving forecasting accuracy and data integrity. My technical skills extend to developing ETL pipelines and automating processes, which have led to a 40% reduction in data processing errors. I thrive in collaborative environments, working closely with cross-functional teams to deliver insights that drive business success.
