Lead Product Designer
Product design and direction for new ventures: Maple, Arca, Logcare and Taryn
• Direct product and design across up to 6 products in parallel, leading a cross-functional team of up to 15 designers and engineers and working directly with the CEO on vision, MVP scope and execution.
• Built a shared design system (tokens, components and patterns for web and mobile) used across the team's products, so interfaces and features move from one product to another with little rework; the team chat runs on it too.
• Designed SmartOps for Arca, an AI copilot that cuts a scheduler's work on each staff call-off from 1–2 hours of phone calls to a few minutes, by ranking who can cover without overtime and messaging them all at once.
• Designed Apply Master Schedule Changes for Maple, one of the platform's most complex features: updating a worker's recurring schedule across 2 months of published schedules went from about 1,000 clicks to 3.
• Designed Ops Agent, an AI agent that watched every Maple schedule for overtime, cost-control rules and staffing targets, and redesigned Maple's scheduling experience and its entire Worker App.
• Took Arca from first commit to a 4-module product in 6 months with a team of 3, and wrote 36% of its 3,704 commits in Next.js, React and TypeScript with AI coding agents (Claude Code).

“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. ❤️
