Abby Castillo is an interdisciplinary artist based in Portland, Oregon. She produces and performs electronic music as abbymachines. Her art is made with a serialized, iterative approach that documents the transformative effects of time. The resulting works compose a modular and recombinable archive of interconnected art. She works with sound, writing, visual art, and creative code.

When not making art, Castillo works as a CRM database administrator. She is currently developing her skills in full-stack web development.
