I’m a senior product designer, design engineer and builder, and artist based in LatAm, I’ve spent the last 12 years creating human-centered experiences that blend technology and art.
I’ve worked with companies like Universal Music, Univision and MercadoLibre, helping take their products from 0 to 1. I collaborate with early-stage startups to bring bold ideas to life.
Outside of design, I’m an artist exploring street photography, writing poems, and producing music.
