The Story
A Non-Linear Path
I didn't start with code. I started with people. Twelve years in hotel reception, first at Inatel Albufeira, then as senior front-desk at 3HB Faro. That taught me how to read a room, stay calm under pressure, and care about the details that make someone's experience feel right.
In 2023 I enrolled at ETIC Algarve to study web programming. Two years later, I joined Dengun as a programmer, building Flutter apps. The path wasn't straight. But the perspective it gave me is something I'd never trade.
