About

Builder first, student second.

I'm a junior Computer Science & Cybersecurity major at Hofstra University who builds full-stack web and mobile products, runs a software studio, and serves in the U.S. Coast Guard Selected Reserves.

I ship real products — from a live B2B marketplace to a feature-rich mobile app — while balancing military service, a full course load, and client contracts. I'm looking for an internship where I can bring this same energy to a team.
