About Me

Explorer at heart, shaping the future of space systems.

I am a sophomore at Case Western Reserve University, pursuing a double major in Mechanical and Aerospace Engineering with a minor in Computer Science. I thrive at the intersection of hardware and software, with an ultimate goal to build the intelligent systems that will drive the future of space exploration. To me, space represents the ultimate boundary of discovery. I bring that same curiosity into my leadership work, where I am dedicated to promoting STEM education and creating hands-on opportunities for youth. When I'm away from the lab or the computer, you can usually find me playing soccer, capturing the world through photography, or working on personal technical projects.

My journey began in Miami, Florida. Growing up in a vibrant environment shaped by my African American and Puerto Rican heritage, I learned early on that collaboration is about truly understanding where people come from to build something great together. Spending my youth kayaking through mangroves and exploring the Everglades gave me a deep curiosity about how the world works on every scale, from ecosystems to galaxies. This natural fascination with exploration eventually transitioned into a driving passion for aerospace, robotics, and complex engineering systems.
