Magallanes is a Los Angeles-based artist working with painting, sculpture, and mixed media. His work often touches down at the intersections of cultural iconography, the folkloric, and the aesthetics of propaganda. His artwork is informed by the cultural and social elements of his upbringing in a Mexican-American barrio east of downtown Los Angeles. At the age of fifteen, he was expelled from high school but was accepted into the Ryman Arts program at the Otis College campus, which encouraged him to become a professional artist.

In 2016 Magallanes founded 3B Collective along with five other fellow UCLA Art students. They have focused on large-scale, site-specific public works. Since then, the 3B Collective has created permanent site-specific and public art projects for the Museo Infantil Oaxaca, UCLA, UCSD, California State University Stanislaus, and is currently working on public works for the Los Angeles County Department of Arts and Culture, University of California San Diego, and City College San Diego.
