Freelance Product Engineer

Thoughtful products.
Built with care.

I build web products with a focus on clear interfaces and maintainable systems. My work brings together hands-on engineering, open-source collaboration and AI-assisted development.

Engineering approach

Understand the problem.
Make deliberate decisions.
Take responsibility for the result.

From interface details to development workflows, I care about how a product works — and how well a team can keep building it.

How I build

  • Product thinking, down to the details

    I connect implementation decisions to the people using the product. Clear feedback, keyboard interactions and predictable behaviour are part of the work from the start.

  • Open-source collaboration

    Working on Zammad has shaped how I approach software: make decisions understandable, review changes carefully and leave code others can build on.

  • AI as part of the workflow

    I work with agent harnesses and reusable workflows as part of my development practice. I define the context, guide the work and review the output — with engineering judgement and responsibility staying with me.

A little about me

I’m Ben, an Austrian product engineer based in Tenerife. I enjoy making complex software feel straightforward and working with people who care about the details.
