How I Work

A few habits I’ve built over the years, each one learned on a real project.

More about me →

In critical flows, I make the intent and consequence of each step visible before the user acts. On SAJ Online, I applied this to extrajudicial hearings and to converting procedures into court cases. For a court-integration status panel, I drafted ten design conclusions with the UX researcher. Two of them: show status per action, and warn before an action fails. I presented the draft to engineering, and the panel was not built.

What Colleagues Say

I've been working with Guilherme at Softplan on the evolution of SAJ Online, a system built for complex judicial and institutional environments. He has a very strong systems-thinking mindset, with an exceptional ability to translate complex problem spaces into clear, scalable product structures. His contributions to information architecture, decision flows, and core product foundations have been key to aligning user needs with business goals and regulatory constraints.

Guilherme approaches product design in a strategic and analytical way, and his input is especially valuable during discovery and prioritization discussions. He's comfortable navigating complexity, works extremely well with PMs and engineers, and consistently keeps both user impact and business outcomes in focus. He's a mature, dependable product designer, with a great fit for data-rich, mission-critical products.
