AI agents build UI quickly, but they can't defend their design choices. Open UX gives them sourced UX rules, so every decision comes with a reason.
Stop agents from inventing UX rules: open-ux.dev case studyyonatan lev ari / ux, ui and design infra lead
I connect product, design and code.
Twenty years in UX/UI and product taught me to look for the patterns underneath. Today those patterns shape design systems, product rules and AI workflows that teams and agents build on.
What I do
-
Building design systems with teams
Tokens, components and the shared language around them.
-
Writing UX specs people actually read
Specs that walk stakeholders and devs to the same answer.
-
Helping product owners think UX and dev
Teaching owners to see flows, states and edge cases.
-
Bringing UX craft into AI workflows
Rules and checks that help agents design with reasons, not guesses.
Selected work
Orchestra
Context and memory don't always carry from one agent session to the next. Orchestra keeps shared memory and skills in one place, so the work builds on itself.

Kee
A rapid-logging journal for iPhone, with boards that turn everyday life workflows into simple routines.

New faces, new work, something to learn. I'm always open to sharing my ideas and experience in the following paths.
Design Workflows with AI Consultation
New tools often bring a new process nobody asked for. Here, AI slots into the process you already have. The steps that work stay, and your team ships faster.
You get a clear map of where AI helps your flow, and where it should stay out.

Product Life Cycle Consultation
Products drift when each stage sets its own bar. I stay from discovery to handoff, so the product keeps one standard. Scope comes first, and ready and done mean the same thing to everyone.
You get one shared idea of ready and done, from the first sketch to handoff.

Design System Consultation
Design and code drift apart when the docs come last. Here the docs come first. Every change lands there, then reaches the product.
You get docs your team trusts, and a product that matches them.
