UX/UIData visualization
Promptly
While working as a Product Designer at a Portuguese company called Promptly, I participated in a project focused on helping healthcare researchers analyze large-scale clinical data. The goal was to enable users to identify which treatments, procedures, and medications produced the best results for different diseases. Although the UX framework was already established, my main focus was on improving the interface design and data visualization, ensuring clarity, consistency, and usability in a complex analytical context.
🎯 The Problem
Researchers needed to explore and compare vast amounts of medical data. The challenge was to translate complex datasets into intuitive visual insights while maintaining visual consistency with the existing design system and supporting accurate decision-making.
💡 My Role
As the UI designer in this project, I focused on refining the visual hierarchy and enhancing the readability of data-heavy dashboards. My main contributions included:
- Designing reusable data visualization components (bar charts, line charts and comparative tables).
- Redefining the visual hierarchy to prioritize clarity and quick interpretation.
- Adjusting the color palette to improve accessibility and contrast.
- Collaborating closely with developers to ensure accurate implementation.
- Even without a formal research phase, I worked closely with internal stakeholders to validate usability decisions and iterate on design details based on team feedback.
Key Findings
- Several elements were not as clear as expected for users
- Accessibility issues were validated
- Designing for two opposite user types within one experience created unavoidable friction
- Longer screens (initially considered a risk) often helped users feel more secure and guided
Outcome
Although the MVP had strong constraints, the team gained crucial learnings that influenced the next generation of C6 Bank investment products. Our research insights helped the company:
- Redefine the approach for future investment features
- Establish a much stronger initial research culture
- Improve design processes and discovery practices
- Build a more scalable foundation for the Investment Funds platform
