Graphic Artist, associated with the APBA (Associação Paulista de Belas Artes) since 1989, where I studied illustration, artistic design, and later design, until 2000. In 2003 I became interested in free software, starting to use Linux and all free software alternatives for graphic creation. At the same time I was contracted by a graphic company as a designer, where I had the opportunity to learn about proprietary alternatives like Corel, Illustrator and Photoshop. I was able to gain a different point of view, and carry a more ample vision into my work through free software. I could make a more honest comparison between all software options, not as free or proprietary, but rather as working tools.

In 2008 I started to collaborate with the distribution of Kurumin Linux, where I created the mascot and began to maintain the graphic interface and appearance of Kurumin until the latest version (7.0), maintained by its creator, Carlos Eduardo Morimoto. passionate for design and principally Vector and Vexel Art, I developed my best work using the vectorial image creation tools. With Inkscape, as well as having completely studied its history and witnessing its development since its earliest versions, I developed work for sites that are referenced around the world. Today I make up part of the Inkscape Brazil and Ogimp free code communities. I am a graphic designer for Hardware.com.br and other companies where I offer graphic design and web services, where I work with free tools on their development.
