Fun Fact: I co-designed a solar-powered glider bench for the University of Miami that features USB outlets and overhead lighting to enhance student comfort and productivity. Our system ran entirely on renewable energy, producing zero carbon emissions and no added electricity costs. Though the prototype was paused due to COVID-19, our approved design laid the groundwork for future campus sustainability upgrades
