Brazilian entrepreneur based in Massachusetts

Patrick
Domiciano.

I turn real problems into businesses, systems and products.

I run businesses, shape experiences and build systems around what actually needs to work. Technology comes in as a tool — not as the starting point.

02How I build

A real problem
can become a system.

I start by understanding what needs to work. Then I turn the solution into a process, the process into a system and, when it makes sense, the system into a product.

I don’t start with the tool.
I start by understanding what needs to work.

It wasn’t just one project. It’s how I think.

05About Patrick

I learned
by building.

I’m a Brazilian entrepreneur in Massachusetts. I didn’t start with software: I started by working.

I worked as an employee in the United States, including as a cashier, and turned what I knew how to solve into services, then into businesses. Technology came from real operations — from what kept repeating, stalling or getting lost.

Is there something worth building?

A business, a system, a product or an idea — if there is a real problem behind it, it’s worth a conversation.
