About
Senior Product Designer with 9 years in product design and a front-end background (2012), focused on e-commerce and mobile at scale: checkout and payments, personalization, retention and social commerce for Nike Brasil, Centauro, Casas Bahia and Hotmart. I work end to end — discovery, research, flows, prototypes, A/B tests, handoff — with Product, Engineering, Marketing and data teams, and I prototype in code and ship with AI.
Today I'm the senior product designer of the Nike Brasil app and site at Grupo SBF, owning the whole journey for two years: onboarding, home, search, PDP, cart, checkout and profile.
What that looks like in practice:
- Review Social — I proposed and designed influencer video reviews as social proof, from collection highlights to the PDP (play CTA, review card, shoppable product list inside the video), for app and web. A/B test: add to cart 16.6% → 21.4% (+27.4%), purchase conversion 19.5% → 23%, 7.7% of orders impacted, projected R$ 9M on the top 50 running shoes. Now rolling out to 100% of users.
- Checkout and payments — Pix journey improvements (higher completion), the full cashback journey built as a platform for Nike and Centauro, coupons at order summary.
- Voice of customer — created the app's program and ran it monthly for two years: store reviews, CSAT and Sentry feedback turned into a problem taxonomy with owners.
- Brand standards for digital — translated Nike's global standards into per-screen guidelines, so Marketing and Product build campaigns inside the product.
- AI — brought IA Labs and Product together and designed the PoC of a generative-AI shopping assistant; built Centauro's influencer action center and its design system with AI.
Before Nike: Via Varejo / Casas Bahia — UX and strategy for one of the largest e-commerce retailers in Brasil; Hotmart — the Hotmart app (Sparkle) and web; Amo Promo — travel tech (insurance and flight comparison), senior designer in a team of four; and five years of front-end, mobile and brand work before that.
Brand systems are part of how I work: Nike Brasil's digital brand standards, the brand design system for Drogaria Araujo's app and site, Amo Promo's style guides, and DSZ — my own brand system behind zezeze.com.br (six moods, a character grid, a generated symbol font), built with coding agents in a reviewed-patch workflow.
