21. That's how old I am. I started coding at 16 and got my first real job at 17, as a Python engineer at a company building systems for hospitals. Real production code and real responsibility, much earlier than most people get that chance.
I stayed three years. I was good at the work. I wasn't fulfilled by it.
So at 20, I quit, packed a bag and moved to Ireland, mostly to learn English, partly because I needed to see what else was out there. I ended up living there for a year. During that year, I met the person who became my partner. She's from Italy. When my time in Ireland ended, I went to Italy instead of Brazil and spent three more months there.
By the end of it, I spoke two languages I didn't speak a year before.
That's also where the name of the company comes from. Sentiero means "path" in Italian. It's not a clever branding exercise. It's literally what that year was.
Now I'm back in Brazil, looking at the European tech job market from the other side: as someone who has lived it, not just researched it.
I'm not doing this alone. My co-founder is my age, comes from sales and marketing rather than tech, and left Brazil for Europe around the same time I did, for his own reasons. Different paths, same direction.
Sentiero AI is a company, not a single tool: we build applied AI products, and Career Copilot, this CV and job match analyzer, is the first one, not the only one. What carries over to whatever comes next is how we build it: nothing invented, and every claim checked against your own file.
No polished pitch: just two 21-year-olds building this in public and figuring it out as we go.
