About Rubik
A UX design process you can defend.
What Rubik is, where it stands today and who is building it.
The product
What Rubik is
Rubik is a web application that guides you through a complete UX design process and validates every deliverable against published principles: Nielsen Norman Group, the Interaction Design Foundation, WCAG, the Laws of UX, Stanford d.school and Material Design, among others. Every finding comes with its source cited.
You start with a 14-question brief and Rubik works out the process that fits your project, from a short sprint to a complete multi-month process. At each step it tells you what to do, the AI reviews what you deliver and Rubik grades it against explicit criteria.
It doesn't design for you. Rubik doesn't replace your judgment: it structures and verifies it. And when a source is missing, it says so instead of making one up.
Why it exists
Consistency is a process problem, not a talent problem.
Design systems keep the result consistent. Nothing keeps the way of getting there consistent.
Decisions get scattered
They live in heads, Figma files and Slack threads, so every project rebuilds patterns from memory, and memory diverges.
Without criteria, everything is opinion
Without an explicit reference, whether a deliverable is good depends on who looks at it. Rubik puts the criteria in writing, with a source.
Generic AI improvises
AI tools often cite principles that don't exist or that distort the source. Rubik validates against a reviewed knowledge base.

Senior Product Designer · Remote from Colombia
I've spent nine years designing high-volume transactional products: e-commerce, fintech and banking journeys, where a small UX decision can move adoption, trust or conversion.
At Mercado Libre I was a Senior UX Designer between 2022 and 2026. I redesigned the entry point for new buyers, with +25% conversion and +8% engagement in a production app across Latin America. At Wolox (Accenture) I designed adaptive banking journeys for BBVA Argentina.
My current focus is the interaction between people and AI: systems that suggest or prioritize while the person stays in control. Rubik began as a personal project from that idea, applied to my own craft: that every design decision has a criterion and a source behind it.
