As a musician, composer, and former guitar teacher, I bring creativity, precision, vitality, and a rigorous, methodical approach rooted in discipline and constant learning to my software development career. True perfection in what we do is unattainable. Yet, some things will always be closer to perfection than others, depending on our will.
I'm professionally fluent in English, native in Portuguese (European) and Spanish (LATAM), and elementary in French.
