About Me

I started my career in the creative world as a tattoo artist, where I learned that precision isn't optional—it's everything. That obsession with detail followed me into software development.

Today, I'm a full-stack developer focused on React Native and TypeScript. I bring an owner-operator mindset I like to build products that work for people.

I'm currently building Hygi, a SaaS marketplace for domestic services, and am multilingual with EU work authorization (Italian citizenship).

What I'm Building

HygiActive Development

A mobile-first marketplace connecting domestic service providers with clients. I'm architecting the entire stack—from real-time booking systems to provider dashboards.
