How I work
I start with the real problem, not the tool. Then I turn the solution into a process, the process into a system and, when it makes sense, the system into a product.
- ProblemUnderstand what has to work in practice.
- SolutionSolve it for real, in real use.
- ProcessTurn what worked into routine.
- SystemGive the process a structure so it repeats.
- ScaleOnly then grow, or turn it into a product.

About
I learned by building.
I was born in the United States and, at two, my parents took me to Brazil, where I grew up. Today I build businesses and projects in Massachusetts. I did not 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 and then into businesses. Technology came from real operations: from what repeated, got stuck or got lost.

Is there something worth building?
Business, system, product or idea: if there is a real problem behind it, it is worth a conversation.
