Product, brand and code, from one designer.

I’m Blaž, a product designer and design engineer in Ljubljana.

Six years in agencies, at Kreatorij and then at Futura DDB, where I became Head of Digital. Then two years shaping every product and the brand at Gaming Systems.

Now I’m building Tessina UI, where what I design is what ships.

What I do

  • Product

    UX and UI for web and mobile, and the design system under them. At Gaming Systems that was all seven products, from a phone to a desktop.

  • Brand

    Logos, identity, marketing and video, so that a product and everything around it read as one. I built the Gaming Systems brand from scratch.

  • Code

    I build what I design, in React and with Claude Code, so nothing is lost in a handoff. Tessina UI and this site are made that way.

How I work

The model writes the first draft. I decide what is worth keeping, fix what feels wrong, and keep it inside the system.

  1. Me

    Design

    I work out the problem, the flow and the look first. Sometimes in Figma, sometimes directly in Claude.

  2. Claude Code

    Brief

    The agent starts from the system, not from a blank page: its tokens, its conventions and the documentation people read.

  3. Claude Code, then me

    Build

    It proposes a plan, and I correct it before any code is written. Then it builds one change at a time, and I send back what drifts from the system.

  4. Scripts, then me

    Check

    In Tessina UI a change is not done until it passes type checks, lint, unit tests and browser tests for accessibility, screen sizes, reduced motion and three browser engines. A screen reader is still listened to by a person.

  5. Me

    Finish

    Nothing is committed until I say so. What gets turned down goes into the component’s notes with the reason, so it is not proposed again: a switch for Monthly or Yearly, for one, because a switch says on or off and neither is off.

Read what the agents read

Tessina UI

My own product: 120 accessible React components that ship in light and dark, on every screen size.

I designed the system and its brand, then built the library, its documentation and the theme editor that goes with it.
