Born in Mexico and currently based in Germany, where he is also a citizen, Sandoval is a contemporary polymath working across artistic handicrafts, sound, and visual arts. His practice spans both analogue and digital media, integrating traditional craft techniques with emerging technologies.

Rooted in a Gestalt approach to creativity, his work investigates holistic and dialectical relationships between Humans-as-Machines and Machines-as-Humans. Through this perspective, he explores on the dialectics of symbolic self-perception. He lives and works primarily in Berlin. His diverse body of work has been commissioned, exhibited, and presented internationally, including in Austria, China, Cuba, France, Germany, Italy, Mexico, the Netherlands, Palestine, Spain, the United States, and the United Kingdom.
