My name is Álex. Brazilian by birth and San Franciscan by heart, I build intelligent systems where thoughtful design matters as much as technical execution.
Classical music has shaped the way I listen. Through piano, violin, and conducting, I keep returning to the same question that draws me to systems built with care: what makes structure feel meaningful.
