About

A little
about me.

I'm a finance data analyst based in Connecticut who enjoys working through the full analytical process, from digging into messy data to uncovering what actually matters and turning that into something teams can use. I primarily work with SQL, Python, Tableau, Power BI, and Excel, and I'm at my best when the end result is a dashboard or tool that helps people make better decisions.

I'm especially interested in problems where the analysis has real impact, where it informs a choice and not just a report. I've built dashboards and data pipelines at Cognizant and am always looking to keep improving and going deeper in my work.
