What I'm looking for

I’m looking for a role where I can build interactive dashboards, automate ETL/reporting, and turn business questions into accurate metrics—supporting faster, data-driven decisions while maintaining strong data quality and governance.

I’m a detail-oriented Data Analyst with a progressive, diverse background spanning analytics and digital storytelling. I collect, clean, and transform large datasets and use SQL, Excel, Power Query, DAX, Tableau, and Power BI to generate actionable insights and automate reporting workflows.

I’ve built interactive dashboards that accelerate decision-making by up to 40%, and I focus on translating business goals into accurate metrics and clear visualizations. From preparing data for consistency to writing custom transformations and measures for advanced analytics, I bring a strong grasp of data-driven storytelling and user behavior.
