Designing Grupo Mateus’s ERP Experience

A complete UX and UI redesign of Grupo Mateus’s ERP system, streamlining navigation, increasing task efficiency, and delivering a mobile-responsive interface for thousands of users.

project overview.

As part of Grupo Mateus’s broader digital transformation, the Sinapse ERP redesign aimed to modernize and humanize the internal platform used daily by employees across departments—from logistics and inventory to finance and administration. My role was to lead the development of the new interface, focusing on improving usability, system clarity, and task efficiency.

To kick off the project, I conducted a reverse engineering process to fully understand the existing platform. This meant diving deep into its structure, workflows, and features, while observing how different teams interacted with it in their daily routines. I mapped user journeys, ran interviews with employees from various departments, and identified key usability issues and friction points. These insights helped form the foundation for a user-centered redesign.

Working from an early style guide, I began shaping a cohesive UI system that evolved into a full design system for Grupo Mateus. The redesigned interface emphasized modularity, responsiveness (including mobile support), and improved navigation, helping users complete tasks faster and with less cognitive load.

Research & Discovery

• Conducted semi-structured and open-ended stakeholder interviews

• Facilitated a Lean UX Canvas session to align goals and pain points

• Benchmarked ERP competitors to extract interface patterns and usability trends

• Identified critical pain points: slow access, outdated navigation, redundant flows

• Created user personas from interview insights (e.g., admin and purchasing roles)

• Defined pain points: excessive clicks, poor mobile access, no task prioritization

Usability Testing

• Conducted a System Usability Scale (SUS) with 140 users

• Diagnosed frustrations: system crashes, unclear task flows, complex logins

• Mapped full User Journey from login to password recovery

key insights.

What Worked Well:
Quick Access features (Recent and Pinned routines) saved users time navigating

• The dashboard layout was praised for being “clean and not overwhelming”

• Mobile flow was perceived as “faster and easier than expected”

Opportunities Identified:

Some users hesitated with icon-only navigation → Added hover tooltips and labels

• One participant tried to search inside the “Recent” box → Added search affordance hint

• In password recovery, a user missed the CTA on smaller screen → Adjusted mobile padding and button size

testing.

To ensure that the redesigned Sinapse ERP dashboard met usability expectations across its user base, we ran a structured remote usability test using Useberry. Our goal was to validate key flows, measure user satisfaction through the System Usability Scale (SUS), and gather both quantitative and qualitative feedback on the final prototype.

key ux wins.

Sinapse was the first project I led from beginning to end, and with that came a big sense of responsibility. Even though the deadlines were tight and expectations were high, I felt motivated to make a real difference. I had the autonomy to explore solutions that would genuinely improve how people worked across the company. What drove me was the opportunity to redesign something meaningful and use data to back up each step, helping stakeholders clearly see the impact.

After the launch, the results spoke for themselves:

• Task completion time dropped by up to 30%
• The newly introduced Quick Access module quickly became the most-used feature
• Mobile usability improved significantly, especially for non-technical roles
• The SUS score jumped from below 50 to 86.4

reflection.

Working on Sinapse taught me a lot about designing for real-life complexity. The system had to serve many roles and workflows, and my decisions needed to balance structure, clarity, and empathy. Every small detail mattered, from how people logged in with their CPF to how easily they could move through the interface without getting stuck.

The handoff phase had its own layers of complexity. The design system was not fully in place, so I started documenting components and tokens as we built them. Different teams were developing parallel products, so keeping everything aligned took time and care. Still, even with a gradual rollout, the foundation we built allowed others to scale the work later on. Looking back, I see this project as a turning point — not just in my career, but also in how design started playing a stronger role inside the organization.
