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.

Featured Work

Intel — Sustainability Impact Analysis

Wrote SQL queries to analyze 601,740 repurposed devices across Intel's global program. Found that older devices save 2.5x more energy per unit than newer ones, and that routing laptops to Asia produces the highest CO₂ return because of how coal-heavy the regional grid is. Built a data-driven recommendation from those two findings.

"Know The Feeling" — ESPN Campaign

Designed a $4M social-first campaign to grow ESPN's prime time NFL audience among younger viewers. The strategy focused on emotion over rules, leaning into creator partnerships, short-form content, and the kind of raw fan moments that actually go viral. Backed by Deloitte and academic research on Gen Z sports habits.

AI in Business and Ethics — Website

Hand-coded a multi-page site from scratch to explain AI concepts to a non-technical audience. Covers practical automation, ethics, and real business use cases with clean explanations and simple demos. Built entirely in HTML and CSS without any frameworks.

Service & Community

British Virgin Islands — worked with a small team to repair a beach sunshade structure and helped with roofing work on a local farm, then spent time with a local animal rescue doing puppy care and deticking.

Dominican Republic — helped build a preschool and ran a community day camp in a small Haitian village, teaching beginner English and organizing daily activities for the kids.
