After more than a decade working as a multimedia designer, he chose to redefine his path in 2014, fully committing to tattooing. His journey began in a self-taught manner, driven by a deep passion for art that has been present since childhood.

Seeking growth, he later surrounded himself with experienced artists who helped shape both his technique and artistic vision. This transition marked the foundation of his career and the beginning of a continuous pursuit of excellence within the world of tattooing.


Alex Ulloa’s work is defined by a strong focus on detail, contrast, and composition, creating black and grey pieces that aim to achieve depth and realism.

Currently based in Aalborg, Denmark, he continues to refine his visual language, approaching each project with the intention of creating meaningful, lasting pieces that go beyond the surface and establish a genuine connection with each client.
