Top SchoolLeo Mcelroy is an independent technologist based in Cambridge, MA, who builds open-source tools and learning systems that help people make things and make sense while doing it. With nine years’ experience across digital fabrication, CAD, and web tooling, he has shipped web-based PCB and GPU-accelerated circuit board design prototypes, contributed UI/UX features to widely used Hack Club projects like the Sprig game editor and site, and published research at the Symposium on Computational Fabrication. He designs educational languages and curricula—authoring the Gram design language and running training programs that produced thousands of reusable masks during a funded civic-response effort—and holds a Watson Fellowship investigating makerspaces globally. Comfortable bridging direct-manipulation interfaces with parametric and programmatic design, he combines hands-on engineering, published research, and community-focused pedagogy to create tools that scale learning and production.
