About
I'm Leo, a senior product designer from São Paulo. I chase the problems nobody has solved yet, and I build the answer myself when I can. I use AI to move faster: I work in Claude Code, set up design QA, and ship vibe-coded solutions with engineering.
I've designed complex digital products for global enterprises and fast-growing startups, across fintech, healthcare, IoT and enterprise SaaS: payment platforms, hospital systems, energy and mobility products, and secure enterprise messaging. I work with distributed teams across the US, Europe, Asia and Latin America.
What I do
- Building with AI
- I use Claude Code and vibe coding to prototype, validate and build production-ready experiences together with engineering. I've created solutions for QA and processes, and rebuilt whole sites with Claude Code.
- AI agents for feedback and research
- I design and build AI agents for design work. They qualify and structure user feedback, support user research and take on other repeatable design tasks, so product and design get insight workflows that scale.
- Design systems and handoff
- Token and variable libraries, component governance and design-to-code handoff, including with the Figma MCP and Claude Code.
- Product ownership
- End-to-end design from discovery and product definition to launch: roadmaps, flows and edge-case logic, defining what to build and why before designing how.
- Design QA
- I set up UX quality assurance that fits how teams ship: review frameworks, ceremonies and operating standards that catch UX and UI issues throughout the product lifecycle.
Beyond design
- Motorcycles
- They are a big part of my life, and I like to tinker with them. On a bike the noise drops away and the next corner is all that is left, and looking after one is a way of paying attention. Vintage restoration and brat-style culture pull me in, and they shaped the look of Outrider. That project started on the road: stopping to check a phone is unsafe, so I moved the navigation to the wrist.
- Japan and Zen
- Japanese culture and Zen Buddhism are a big interest of mine. The Fun page explains zazen, seated meditation, and has a timer if you want to sit for a few minutes.
- Crossfit and martial arts
- I spend my days with words, screens and opinions. Crossfit and martial arts give me feedback nobody can argue with: the weight moves or it doesn't, the technique lands or it doesn't. The body learns on its own terms, through repetition and small corrections, and it knows things I could not get from reading.
