/about
I am mr. grassho (formerly Victorio Scafati), a technical leader focused on payment products, open banking infrastructure, backend systems, and security. I write here about security research, infrastructure, hardware experiments, and software projects.
My work sits between product strategy and engineering execution: designing payment architectures, reviewing software systems, leading backend teams, and building reliable financial APIs.
I also make electronic music under the Vicson alias and play saxophone and flute. In mid-2024 I released CASA VALLEJO, an album that blends house, jazz, and soul with poetry by Cesar Vallejo.
