Mini Cases
01 - Applying Visual Hierarchy in the Medical Record
Challenge
The medical record screen — which replaced traditional paper forms — was long, unorganized, and difficult to navigate for different user profiles (doctors, nurses, managers, etc.). The legacy front-end framework was rigid and limited layout changes, resulting in a confusing and tiring experience.
Solution
I created a modular approach focused on visual scanning and organization. I restructured both the system’s main header and the secondary header (specific to the medical record), ensuring harmony between navigation levels and reducing cognitive load.
I implemented containers with prominent titles, visual breathing space, and strategic field distribution — enabling each professional to quickly find the relevant sections without clutter or visual noise.
Impact
The new hierarchy streamlined workflows across user profiles and became a visual model for other screens in the platform.
The modular structure improved consistency and accelerated design and development decisions.
According to internal reports, one client acquisition was influenced by the positive perception of the redesigned interface.

02 - Geospatial Indicator Map for Public Management
Challenge
How to present complex urban data (population, health, education, infrastructure, real-time health incidents) in an interactive map that is accessible and meaningful to public managers with varying levels of knowledge?
Solution
I participated in the entire cycle — from discovery to MVP — collaborating with the CEO, PO, and healthcare specialists to understand how to cross-reference public data (like IBGE) with internal company databases.
The main goal was to organize dense, mandatory information on screen in a clear and actionable way. I structured the interface using visually distinct sectors, ensuring scannability and accessibility to critical information.
General and area-specific data panels were positioned side by side, enabling quick comparisons and visual context. I applied precise information hierarchy, prioritizing what was most relevant for decision-making.
I created quick wireframes on paper and directly prototyped in Figma, using high fidelity and interactive logic (variables and conditions) to simulate a realistic experience for market presentations.
The maps allowed users to explore data by city, property, resident, or health events like dengue outbreaks — with interactive filters and georeferenced visualization.
Impact
The MVP was well-received by potential clients. The highly navigable interface and unified visual identity (also developed by me) reinforced perceptions of innovation, clarity, and professionalism.
The tool helped transform dense data into actionable and user-friendly city health diagnostics — becoming a strategic and intuitive resource for decision-making in the public sector.

03 - Rebranding Visual com Psicologia das Cores
Challenge
The dominant orange color in the system caused eye strain and made reading difficult during long sessions. The contrast between text and background violated WCAG accessibility guidelines — especially for health professionals working extended hours.
Solution
Based on WCAG, color psychology, and recurring discomfort reports, I proposed replacing the orange with a teal tone — evoking balance, health, and calmness.
The change aimed to improve both visual comfort and product perception, enhancing clarity and user trust.
Impact
The new palette was widely approved and adopted as part of the platform's overall branding. Professionals reported reduced eye fatigue and greater comfort during daily use. The new color scheme also improved perceptions of modernity and trust in the system.

04 - Responsive Design for Field Use
Challenge
The Saúde Digital platform was primarily used on desktops, but primary care professionals conducted home visits — requiring a functional experience on tablets or phones. Navigation on mobile broke the layout and hurt usability.
Solution
While mapping the flow of a module intended for tablet use by community health agents, I identified that general settings and navigation headers made it difficult to access both this new module and other system screens.
I redesigned the two main headers, adapting them for mobile devices with a focus on responsiveness, accessibility, and touch interactions. Despite technical stack limitations, I tailored the design to the system’s real capabilities, ensuring consistency and functionality.
Impact
The new structure made field use easier for primary care professionals, with smoother and more accessible navigation.
Although not field-tested directly, the updates were validated by the QA team and praised internally for improving consistency across devices — reinforcing the platform's versatility.

05 - UX Research Training for the Product Team
Challenge
User research was based on direct and explicit requests, making it difficult to deeply understand real needs and usage contexts. This approach limited insight quality and reduced the accuracy of proposed solutions.
Solution
I created an educational infographic and led a didactic presentation for stakeholders. The material, delivered via Figma and PDF, explained how to extract meaningful insights based on user pain points, behaviors, and motivations — not just stated desires.
I included examples of strategic questions, interview best practices, and active listening techniques, promoting a more empathetic and investigative mindset within the UX research process.
Impact
The material was well received and led to real change in how teams approached user conversations. Focus shifted from gathering requests to uncovering context and motivation — increasing product delivery quality and empathy during discovery.

06 - Smoothing the Multi-Step Login
Challenge
The first-time login flow had four steps. Beyond the perception of a long wait, the interface lacked visual consistency, had low aesthetic appeal, and looked unprofessional — creating friction right at the entry point of the platform.
Solution
I implemented a new final login screen with a blurred image of the system in the background — visually simulating that the user was already “inside.” This anticipation reinforced the sense of progress.
I also standardized visual elements (icons, colors, typography) based on heuristics like system status visibility, consistency and standards, and minimalist design.
Impact
The new design conveyed greater professionalism and trust, improving users’ first impressions. The interface was well received internally and became the visual standard for other login screens.
Validated by the QA team, the new experience brought more clarity and comfort, reducing the perception of slowness — even though the real loading time remained unchanged.

07 - Standardizing Handoff with Figma and Strategic Documentation
Challenge
The absence of a standardized handoff process between design and development caused confusion, visual inconsistencies, and rework. Issues like misaligned spacing, colors, iconography, typography, elevations, and interaction behaviors were frequent.
Solution
I implemented Figma as the official tool for design and documentation. Before the arrival of Dev Mode, I manually documented visual rules, tokens, behaviors, and interaction flows.
With the inspection mode in place, the process became simpler — but I continued adding contextual notes and interactive prototypes for critical flows and microinteractions. All tasks were integrated with Jira, ensuring clear traceability between design and development.
Impact
Standardizing Figma usage increased visual consistency, reduced ambiguity, and improved team productivity.
With less rework and stronger alignment between design and devs, deliveries became more fluid and predictable.
Beyond development, Figma also strengthened strategic work for the product team and stakeholders — facilitating validations, co-creations, user journey mapping, flowcharts, and scope definitions. It became a central tool for both interface design and tactical planning.

08 - Research Repository for the Product Team
Challenge
The team faced communication breakdowns between internal departments and end users. Feedback was fragmented, lacking context and depth. There was no structured research repository or a clear culture of active listening.
Solution
As a personal initiative, I designed a UX Research platform with a dual architecture: on one side, users could submit spontaneous feedback, express frustrations, and offer suggestions in a welcoming space; on the other, the internal team accessed a dashboard with categorized, visual, and actionable data — streamlining analysis, metrics, and decision-making.
There was intelligence behind the categorization steps: a guided question flow worked like a remote UX interview, generating qualified data that revealed not just the issue, but also the user’s pain and context.
The MVP was developed in Figma, FlutterFlow, and Firebase, featuring 77 responsive screens. It followed accessibility principles and had a scalable database structure. Visual elements like icons, colors, and grouping helped users with low digital literacy navigate — validated through real tests, including one with a visually impaired person who praised the visual category cues.
Impact
The initial presentation revealed real communication issues and caught the team's attention. The project was approved as an experiment but not integrated into the system due to fears of receiving too many complaints.
Even so, it sparked internal discussions about user-centered culture, innovation, and knowledge organization.
