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 with databases. She is currently developing her skills in software engineering.
