Mana Gate
A platform for organizing Magic: The Gathering collections and decks, combining prices, statistics, and context for every decision.
View caseSenior Product Designer + AI Product Builder
Design that thinks.AI that builds.
I combine product strategy, interaction design, and AI-assisted development to turn difficult ideas into products people can actually use.

Finished products show what survives reality. Experiments expose the decisions behind what comes next.
Products that
survived reality.
Research, product decisions, and implementation working together under real constraints.
XR Designer
A browser-based studio for composing interactive augmented-reality scenes and publishing them to a link or QR code—without code or a native app.

Dreampaper
A personal production app that streamlines my daily AI image-generation workflow around speed, repeatability, and high-volume creative work.
View caseA lab for questions worth making tangible.
Independent PoCs, interface tests, and technical exercises. Each one isolates a question before it becomes a product commitment.

Across design,
technology, and
new ways of building.
I partner with ambitious teams to solve difficult product problems. My edge is the overlap of design clarity, technical fluency, and practical AI-assisted development.
My experience spans mobile applications, SaaS, games, and extended reality. I make complex systems understandable without simplifying the wrong problem.

Human-led / AI-accelerated
Build.
Inspect.
Decide.
Clients stay inside the making loop. AI shortens the distance between a decision and something we can inspect, critique, and improve.
The goal is not more output. It is more useful iterations before committing time and budget.01Align
Frame the real problem together.
We begin with business context, user needs, constraints, evidence, and what cannot be compromised. Before choosing a solution, we agree on what the first version needs to prove.
A shared problem frame02Build
Make the first proof tangible.
I turn decisions into a working interface or product slice early. Claude Code and Codex accelerate exploration and implementation while I keep the product logic and design direction coherent.
A working proof03Critique
React to the real thing.
You respond to something you can see and use. Feedback becomes specific—hierarchy, copy, motion, behavior, and tradeoffs—so weak or generic ideas are removed quickly.
Specific decisions04Verify
Refine, test, and ship.
We check responsive behavior, accessibility, performance, and technical feasibility. Then we ship the strongest version, capture what we learned, and choose the next hypothesis.
Evidence for the next moveWho owns what
Client
Context, priorities, constraints, domain knowledge, and final judgment.
Renato
Framing, synthesis, product decisions, design quality, and orchestration.
AI
Exploration, implementation, refactoring, production support, and QA assistance.
AI increases the number of useful iterations. Human judgment decides which ones matter.
From intent to a
working first version.
AI-assisted development
I use Claude Code and Codex to turn product decisions into working software, shortening the loop between intent, implementation, and validation.
−Digital products and SaaS
I design flows, interfaces, and systems for web and mobile products that need to balance clarity, scale, and business results.
+Prototypes and proofs of concept
I build testable versions early, reducing the distance between a promising hypothesis and a decision grounded in real use.
+XR experiences
I investigate interaction, ergonomics, and context for augmented reality, virtual reality, and spatial-computing products.
+Ideas under construction.
