Hi there! My name is Guilherme.
I’m a Senior Product Designer based in São Paulo, Brazil, with over 12 years of design experience.
I began my career in graphic design and art direction, learning how to communicate ideas clearly, work with constraints, and deliver with craft in fast-moving environments.
Across my career, I’ve worked throughout the product design process—from research and problem definition to interaction design, prototyping, validation, and design systems. This experience helps me understand each context quickly, choose the right methods, and work with product and engineering teams to deliver useful, scalable solutions.

WHAT I BRING
View this section as:
My process starts with understanding
what the context requires.
Different products require different kinds of design work. I identify where design can create the most value and adapt my role—from researcher and product thinker to hands-on designer, facilitator, or systems builder.
01
Find where design can help
I look beyond the initial request to understand users, business goals, product, organizational dynamics, and technical constraints.
UX Research · Data Analysis · Problem Framing · Stakeholder Interviews
02
Create clarity and alignment
I structure complex problems, make trade-offs visible, and help multidisciplinary teams move toward a shared direction.
Product Strategy · Systems Thinking · Facilitation · Stakeholder Alignment
03
Explore, test, and deliver
I move between strategic thinking and execution, transforming direction into flows, interfaces, prototypes and experiments.
UI Design · Interaction · Prototyping · Usability Testing · A/B Testing
04
Build for quality and scale
I work closely with engineers to create accessible, consistent experiences and reusable foundations to scale the product.
Design Systems · Accessibility · Responsive Design · Developer Collaboration
AI as a working layer
I use AI where it can improve the quality or speed of the work—from research synthesis and exploration to functional prototypes. I also design AI-powered products used in real organizational contexts.
AI Product Design · Research Synthesis · AI-assisted Prototyping · Figma Make · Claude Code · Gemini Enterprise

Different companies, scales, and constraints. The same ability to understand what matters and adapt the work around it.

MY PERSONAL SIDE
Music is my other way of making things.
I'm passionate about music, I sing, I play the guitar and I compose some songs, this is my favorite hobby. You can check some of my songs on my Spotify profile.
I also love to watch some sports, loke football, american football and tennis. And as almost everyone these days, I like watching some series, my favorite ones are Breaking Bad and Lost.
That balance also says a lot about how I approach design.
