Tinker
A handheld for indie games. The page shows your own itch.io shelf before the specs, opens the device in a 3D teardown and lets you play a game before you reserve.
Victor Cavalcante, Product Designer (UX/UI) and front-end developer
6 years in product design and UI/UX, across B2B and B2C. I've built games, gamified experiences, mobile apps, websites, software and CRM, from UX research and wireframes to design and code. Creative enough to jump into whatever comes next.
Featured case study
A smart ring I made up to plan a full launch: who it's for, what the page must answer, how the 3D story moves and what happens after the click.
I started with two proto-personas: a tired professional who wants better sleep without tracking homework, and a runner who needs to know when to rest. Both get the same promise, right in the hero: Rest, measured.

I listed what people ask before buying, like "will I even notice it on my finger?", and gave each question its own section, in the order it comes up. Material answers comfort: 4 g and 2.4 mm thin.

The 3D ring follows a motion script I wrote before building. It turns edge-on for material, faces you for the sensors and draws a charge arc for the battery. Each pose answers the claim beside it.

A plain waitlist only asks. Here two quick questions build a personal sleep plan, and only then does the page ask for an email. Both answers turn into CRM segments.

Choosing a finish, opening a section, finishing the quiz: each one is a named event. I planned ten of them, plus the lifecycle stages and the emails each segment gets after sign-up.

After launch I measure. What works goes into the system; what doesn't goes back to research.

I'm Victor, but everyone calls me Vk. I started in game design, and it still shapes how I work: I look for the moment someone hesitates and ask what would make the next step feel obvious, maybe even fun.
I led a team of four designers across 13+ products in education, health and construction. From 2025 to 2026 I owned the gamification of three regulated consumer brands, from research to code, and led the 4Play redesign that was later presented as a reference in Europe, Cyprus and Latin America.
For recruiters
Open to remote product design and UX/UI roles, full-time or contract. Available now.
I'm in Brazil (UTC-3): full overlap with US Eastern hours and about 4 hours with Central Europe. I work in English every day.
Yes. I'm available now for full-time roles and contracts.
Both. My main role is product design and UX/UI. I also build front-end in React and Next.js, so handoff is short and I can ship small fixes myself.
Education, public-sector health and construction software, indie games, and since 2025, regulated consumer platforms in sports and casino.
“From day one, Victor stood out as an extremely talented and dedicated UI/UX professional. His ability to understand user needs and translate them into intuitive, compelling interfaces is truly impressive.”
“Clean, well-structured, and clearly built with implementation in mind.”
“His ability to see the bigger picture while contributing thoughtful ideas helped us make better decisions and deliver stronger results.”
