CTO & Software Engineer, Barcelona

Portrait of Marcos Aguayo

I design, build and run the technology companies depend on, from backends and cloud platforms to AI, computer vision and robotics. Fifteen years of shipping software. I co-founded Insectius and MiCuento, and I work best with startups and industrial teams whose problem is as much about the business as about the code.
