Creating a unified design system and digital experience for Portal Único, enabling government services to be delivered through a consistent, accessible, and scalable platform.
Portal Único is a national digital platform designed to centralize access to public services for citizens and businesses. The initiative aims to simplify how users interact with government services by bringing multiple processes and information sources into a single digital environment.
To support this vision, the platform required a cohesive user experience capable of serving a wide range of services while remaining easy to navigate, accessible, and scalable over time. Our team was responsible for designing the design system that would serve as the foundation of the platform and using it to build both public-facing pages and authenticated service interfaces.
The main challenge was creating a consistent digital experience across a platform that would support many different services, user journeys, and types of information. Government platforms often evolve through separate projects, which can result in fragmented interfaces, duplicated UI patterns, and inconsistent navigation structures. For Portal Único, it was essential to establish a unified framework that could:
We adopted a design-system-first approach, focusing on building the foundation before designing individual interfaces. The first step was defining the core design foundations, including typography, color systems, spacing rules, layout structures, and accessibility principles.
On top of these foundations, we created a modular component library that included navigation patterns, form elements, content containers, notifications, filters, and interactive elements — documented to support collaboration between designers and developers.
Once the system was established, we used these components to build the platform's interfaces, including both public pages and authenticated service environments, ensuring all parts of the platform shared the same design logic and interaction patterns.
The result is a scalable digital platform built on a unified design system that enables consistent and efficient development of government services. By using reusable components and standardized interaction patterns, the platform provides a cohesive experience across all pages and services.
Portal Único now has a solid digital foundation that supports accessibility, usability, and long-term scalability across the entire platform.
