My name’s Brian DeSousa! I was born and raised in New Jersey by two great parents who immigrated from Portugal. They instilled a curiosity in me for all kinds of things, but particularly computers & markets, from a young age.

I graduated from Cornell University with a B.A. in Economics, minoring in Information Science; while there, I also gained a passion for music production & composition. In the years since college I’ve worked at the intersection of data, marketing, and AI with Fortune-500 corporations like Marriott & UnitedHealth Group.

Both of my Parents are Portuguese (from Portugal!), so I've spoken it from the around same time I learned English.

I was born & raised in the United States and speak English as a first language!

Dates: Sep 2013–Jun 2017

I grew up in Holmdel, New Jersey and attended the public school system from a young age all the way up through high school. That peaceful town and the great people that filled it provided a great foundation for my interests in subjects like computers, markets, and language.

Dates: Aug 2017–Dec 2020

I entered Cornell University in the Fall of 2017 as an engineering student pursuing Computer Science. After my first semester, I knew I wanted to switch gears and pursue Economics so I started taking the required courses and writing a million emails. Three years later in December of 2020, I graduated with a B.A. in Economics and a minor in Information Science.

Projects

Agentic AI Group

In Q1 2026, I began combining agentic AI and Power Automate to bring out a new level and depth of insights into the vast marketing performance datasets we had been working with in DOMO; these efforts ultimately culminated in several agents I built & presented at our annual summit, where we spoke on agentic workflows to the broader organization — I’ve since been selected as part of the 1% of the company that forms our “AI Champions” team, coordinating & connecting initiatives across the business

Campaign Information System

Last year at UHG I built a campaign information system based on naming conventions that replaced our previous encyclopedia, greatly reducing failure points and serving as the foundation of a new & dynamic approach to performance reporting going forward; this project was a cross-org data effort that involved a significant degree of collaboration and planning among different teams

Executive Insights Reporting

At Marriott I was given the task of building various views of business performance results - one of the longer term projects this culminated in was a series of dynamic dashboards in Adobe Analytics and Power BI that provided reporting for a number of stakeholders; using the formula/filtering capabilities to their utmost in each platform, we were able to set a flexible foundation for a range of business needs.

Phoenix Data Migration

I took on the project of migrating our marketing data into DOMO in 2022, and constructing a campaign encyclopedia that would build a platform for future reporting and optimizations. We onboarded dozens of partners across channels like paid search, display, affiliate, and social — all connected with back-end conversion numbers that allowed for a vivid picture of performance and constant insights
