about me

I work where code meets aesthetics: transforming real business needs into functional and visually striking interfaces.

Art has been present in my life since childhood. This artistic background is not separate from my technical work, it is part of it. It is what makes my interfaces stand out by having their own identity.

ink & art

Since childhood, art has been what drives me. Long before code, there was the sketchbook. And that is exactly the perspective I bring to every project I create.

The same attention that guides a needle on skin is what defines every pixel of an interface. My artistic background is not a separate hobby, it is what sets me apart as a developer.
