Founder & Product Builder · Austria

I build products and ship them.

Product direction, UX/UI and development, from the first decision to a public release.

What I actually do.

I turn early ideas into products people can use: direction, interface, build and release.

  1. Product direction

    Problem, audience and priorities. A clear direction before production starts.

  2. UX & UI

    Flows, visual systems and interfaces shaped around real use.

  3. Mobile development

    Flutter products from first build through release on iOS and Android.

  4. Web & brand

    Identity, language and websites that give a product a credible home.

  5. Launch

    Beta feedback, store presence, publishing and work after version 1.0.

Work, not promises.

Two shipped projects. Clear roles, real interfaces and links to the live products.

All in on Starpolar.

It is live on iOS and Android, and most of my time goes into what comes after version 1.0. That is where the work is, so that is where to look.
