Hi there! I'm Carlos De Leon, a Software Engineering student currently in a development internship at a tourism tech company serving Mexico and the Dominican Republic. Transitioning from 10+ years as a Restaurant COO and General Manager, where I led teams of 100+ people and managed operations with $1.5M USD monthly revenue at 30% profit margins.

Today, I'm building responsive web applications with React, Next.js, Astro, Tailwind CSS, and Firebase, focusing on clean code and intuitive UI/UX. My operations background brings proven project management, data-driven decision making, and high-pressure performance skills to every technical challenge I tackle.
