I work with companies, startups and founders by project. I research, design and build the product, with no handoff to another team that redoes the design: what you approve in the prototype is what goes live.
Each one with a case study on this site, so you can see how it went.
I help decide what goes into the MVP, design the screens and build it: a store-published app, an admin panel and a website. You validate with real users before paying for the whole product.
VESS Studio: from proposal to the App Store in 12 weeksI run a UX audit (flows, heuristics, usage data and talks with users), rank what costs the most and redesign it. When it makes sense, I implement it myself.
CuidaMe: an app stuck for 2 years, ready for beta in 7 daysA custom-designed company site or landing page, fast and ready for Google and AI assistants: technical SEO, structured data and consent-based analytics.
Tutory: new website in 63 days, Lighthouse 100I join as the designer who codes: a design system, interactive prototypes to validate or sell the idea, and screens in React and TypeScript ready for production.
HyperGestor: brand, website and ERP, by one personYou pick the stages; not every project needs all of them.
The problems that cost your product the most, with evidence and a priority order, so you know where to start.
Not just Figma images: a prototype you can use on a phone and a computer, to test with users or show to partners and investors.
High-fidelity screens plus documented components, colors and copy, so the product can grow without losing consistency.
Front-end in React, Next.js, Astro or React Native (Expo), connected to the back end (Supabase or the API you already have) and shipped.
Fast, accessible pages with structured data, so they get found on Google and cited by AI assistants.
AI features (assistants, search, automations) designed for the people who use them, with controlled cost and tests before release.
From the first brief to delivery — with feedback and metrics at every stage.
I understand the business, audience, and goals. User research, benchmarking, and defining the product direction.
Interview synthesis and competitive analysis with LLMs
Information architecture, design system, and high-fidelity screens. Rapid iteration with usability testing.
AI-generated layout and copy variations in minutes
I turn design into responsive, performant React/TypeScript code, integrated with APIs — no handoff.
Code agents for scaffolding, testing, and code review
Testing, final adjustments, and monitoring with analytics and A/B testing to validate product impact.
Automated evals and continuous monitoring with agents

Both. I take fixed-scope projects for companies, startups and founders, in Brazil and abroad, and I am also open to remote roles on product teams.
It depends on the scope. After a conversation about the problem, I send a proposal with scope, stages, timeline and price. On a tight budget, we start with what unblocks the most: a UX audit or a prototype to validate the idea.
A UX audit takes days. An interactive prototype, from days to a few weeks. An MVP with an app, a website and an admin panel takes a few months: VESS Studio, with all of that, shipped in twelve weeks.
Both. I design in Figma and build in code (React, Next.js, Astro, React Native). If you already have a development team, I deliver documented design and follow the implementation.
No. Many people come with just the idea or a list of user complaints. The first stage is turning that into scope: who it is for, what problem it solves and what comes first.
Yes. I have worked for clients in the UK, the US and Kenya, in English and remotely, on Brasília time (UTC−3).
Send me an email or a WhatsApp message about the product and the problem. I reply within 24 hours and we set up a call.
