International Business & Analytics

Turning Data and Real‑World Experience into Insight

I'm an International Business student at CU Denver with a 3.9 GPA and a minor in Business Analytics. This past spring I interned with the Downtown Denver Partnership, doing GIS-based economic analysis on 300+ commercial properties and working directly with brokers and property managers to improve data accuracy. Before that I spent two years at Chatham University building a foundation in global markets, accounting, and statistics.

My background is a pretty weird but useful mix of things: geospatial analysis, managing lifeguard teams, volunteering in the Dominican Republic and British Virgin Islands, and building websites from scratch. It all comes back to the same thing though. I like figuring out how messy situations work and making them work better. I'm bilingual in English and Spanish and active in FAM and ALPFA at CU Denver.

Lately I've been exploring how data and strategy play out across finance, consulting, economic development, and client solutions. I'm drawn to roles where analytical thinking and people skills both matter.

Currently: completing the FAM program & building this site
