app concepts, interfaces, code: wholehearted, from the big picture down to the smallest detail.

My principle

I see software as interactive storytelling. Its dramaturgy decides when things appear: every function, every piece of information at the right moment, exactly when you need it.

For twenty years I passionately produced and directed documentary films. Today I do the same with apps: one vision, from the first idea to the live product.

the best software is the kind you forget you're using.

My offer

I design and build whole apps.

From the first conversation to the live product. One person carries the whole arc. No handoffs, no translation loss: the person you talk to is the person who builds it.

I create for

Web Desktop Mobile

For companies and agencies

Available by the day as design engineering capacity inside their team. Or a whole project under their own name.

Already have an AI prototype? I turn it into a real product.

Specialties

Unstructured data

scattered documents and archives become usable knowledge – prepared in vector and graph databases.

Intelligent search and recommendation

finding by meaning, not by keywords – with custom-built algorithms.

AI applications

AI woven into real workflows, under human control.

And in everything: the client decides where data lives and models run – with the big AI providers, on European servers, or on their own infrastructure.

My approach

Films are never completed, only abandoned, George Lucas said. Software is different: it keeps evolving. So I work in a loop, not a line, and enjoy improving rather than abandoning.

  • conceptlistening, research, the story of the product
  • designprototypes, tested with real people
  • codeAI-native, built to be understood
  • deploylive, measured, refined
  • learnwhat users do shapes the next round

My work

I build apps from the visual side out: the experience of thirty years of visual work behind every interface.

Four products. All live.

knowledge has always lived in stories.

About me

Portrait Dodo Hunziker

Trained as a graphic designer. Designed for the web when it was young. Studied film in Prague. Produced and directed documentary films for cinema and television. Founded Filmium in 2023. From the still image to the moving, from the linear story to the interactive. Today both are one: design engineering. What makes this newly possible is AI-assisted coding: it clears the mechanical work, so I work from abundance, design and dramaturgy and code in one flow.

do2 is one person by design and never becomes a bottleneck: when a project needs more hands, or has to keep moving while I am away, I bring in freelancers and specialists I have trusted for years. All under my direction.

software should serve people. not the other way around.
