Stef LiashukFounding product designer
Founding product designer · Paris

I take AI products from zero to the version a team builds.

I lead a product end to end from zero, then build the system and the team around it. 10+ years in product design, most recently Design System Lead at Dailymotion, before that Cognite and Xeneta in Oslo. I design and build with AI.

Zero-to-one products

Products I led from the first sketch: research, UX, visual design and working prototypes.

01 · Pointer Health · Freelance 2025–26

A health forecast for dogs, told by their vet.

I redesigned an engineer-built prototype into a product vets could trust, built the design system behind it, and designed the print for two AVMA conferences.

02 · Oneira · Own product 2026

A dream companion that never tells you what it means.

Five AI characters, four built on published dreamwork methods and one that prepares notes for therapy, ask instead of interpreting. Research, UX, visual design, copy and the prototype build are mine.

Complex systems and data

Design systems and data-heavy industrial tools, used by many teams and thousands of work orders.

03 · Cognite Maintain · Lead product designer 2021–22

Thousands of work orders, one plan a team can move.

From a side concept to the live app: the plan became the workspace, and the Gantt, the network map and the table became views of it.

04 · Dailymotion · Design System Lead 2023–26

One design language for every team, then AI that works inside it.

Tokens, governance and training across native, web, Player and Studio, then design systems that AI tools can read.

05 · Cognite · Design System Lead 2020–22

One designer to a funded team, one system for every app.

I turned a one-team code library into Cognite's company-wide design system, replaced Ant Design with it, and made the case that got it a team.
