“I can say unequivocally that Gui has a mastery of how to create modern, eye catching web interfaces, and also that Gui is both creative and gritty enough to solve any problem that get in his way, particularly when it came to writing code himself.”
“Gui (Guilherme) is one of the most incredible UI/visual designers I have worked with in my career thus far. With this understanding of how design meets function, Gui can be your go to person when it comes to designing unique, beautiful and functional web/mobile applications.”
“As a Jr. Designer, I looked up to Gui and his abilities all the time! He has a gift of elevating platforms and their visual quality through his designs. He has an high attention to detail as a designer, which shows in his designs and his documentation.”
I refuse to believe we have to choose between a beautiful design and a functional product. So on every project, I work to deliver the best experience with a delightful, modern design.
That same drive made me a designer who loves to code. It lets me balance engineering effort with high-quality delivery, always pushing for pixel-perfect solutions that are also efficient and scalable.
And if you made it this far, maybe you're interested in something more personal? 🙂
I'm a musician and I love to play the piano. I'm also into photography, especially of nature, my wife and our twin daughters. ❤️
