Blue Zones are the regions of the world with the highest numbers of healthy centenarians, mapped by researcher Dan Buettner. From this research came Centeni's symbol: a blue pearl. The pearl symbolizes what we hold most valuable and precious: our health. I broke the 2D-symbol rule because Centeni is digital-first.

When you get a PDF of your test results back, it's almost impossible to understand how healthy you actually are. Black-and-white pages, no summary, no context. As founding designer, I decided to show a single number on the home screen, biological age, instead of the full dashboard. 85% of users understood their health better, 79% changed their behavior, and 77% would recommend Centeni.

Google Prism is Google's internal platform for reviewing and classifying user-generated content across its products. As part of the Work&Co team, I designed moderation workflows that helped reviewers make faster and more consistent decisions while handling complex trust & safety cases. The project required balancing usability, operational efficiency, and policy requirements in a high-scale environment used by teams responsible for keeping Google's platforms safe.

"Limite da Conta" ("Account Limit") is a credit product automatically activated when a customer opens an account. The biggest source of confusion: a 5-day interest-free bonus period that, once it expired, retroactively charged interest on the entire period, plus IOF (Brazil's financial transactions tax) charged on a different date and amount than the interest itself. I redesigned it around two familiar mental models: a credit card statement and a mobile data/internet package bonus. Activation within 7 days rose from 17% to 24.4%, and the portfolio grew from R$5.6MM to R$9.3MM.

We identified that customers were canceling without understanding that "Limite da Conta" was meant as an emergency resource for cash flow. They saw the product as dangerous, synonymous with debt and high interest, rather than as protection. Instead of adding friction to the cancellation flow, I repositioned the entire experience and validated it with an A/B test. Churn dropped from 0.36% to 0.25% in one month.

We tested 12 prototypes over 2 months of field research in São Paulo before launching Banco Pan's digital account, shortly after BTG Pactual took over the bank. I identified a 12-second loading bug and resolved it with engineering, and incorporated a scroll gesture that one user had invented into the product. We launched a brand-new bank from scratch in 6 months. A year later, the customer base jumped from 1.3MM to 6MM clients.

I co-founded the company with my wife two years ago and led the brand build from the ground up: visual identity, digital product, and commercial and financial positioning. We sold our first property within twelve months, validating the model.

Camicado's physical stores always had concierges, sales associates trained to understand each customer's taste. The e-commerce side never had that. I conceived themed and brand pages that recreate that curation on the website, plus, in the app, a shoppable video feed and a gift finder driven by personality sliders. Average order value grew 10% in the six months following the site's launch.

Lemon needed a brand that conveyed the trustworthiness of an energy provider, not a startup. I created a new symbol, typography, and color system, designed together with the app's iconography. The biggest design challenge was visual: explaining why one electricity bill turns into two, without making it feel more complicated. The solution was a simple bar chart, with no text at all.
