What I'm looking for

I’m looking for a role where I can build and govern data-quality-first dashboards and analytics—turning complex datasets into structured, repeatable insights that leadership can act on, while partnering cross-functionally to improve decision-making and operations.

I’m a results-driven Data Analyst and “Insight Architect” with a foundation in Applied Mathematics and Statistics, and over two years of experience building reliable, business-focused analytics. I translate disconnected, messy datasets into clear decisions—designing dashboards, running exploratory analysis, and delivering data-driven recommendations across sales, healthcare, cybersecurity, and consumer research.

In recent work, I built a Power BI star-schema to analyze 8,800 CRM sales opportunities and refocused a growth strategy from win-rate coaching to pipeline generation. I also modeled hospital revenue across merged sources to surface payment-status bottlenecks, uncovered key consumer drivers and brand-switching risk, and used Power BI to highlight cybersecurity incident response times lagging behind rising attack volume—pairing technical rigor with business-ready insights.
