Augmented product designer and practical AI tutor in Berlin.
I am an augmented product designer and practical AI tutor. I design and build digital products with AI assistance, then turn what works — and what fails — into tutorials, workshops, and training. Practice makes the teaching credible; teaching makes the practice transferable.
Practice and teaching
Code:Emotion supplies the design discipline. Human in the Middle makes the method teachable. AAA provides working proof.
Design
The design foundation: product thinking, interfaces, visual systems, and thirty years of judgment behind the products and the teaching.
AI framework
The framework and teaching practice: decide what to automate, what remains human-owned, and where review belongs. Arthur's AI Lab and HITM Labs make the method learnable.
Working proof
AAA is where the claim meets daily use: native applications conceived, designed, built, tested, and maintained with AI assistance while product judgment remains human-owned.
Credibility loop
I teach from work that has consequences beyond a demonstration. AAA provides the working record: product decisions, interface logic, model-assisted implementation, bugs, corrections, release gates, and daily use.
Arthur's AI Lab shows how I explain that practice. HITM Labs turn it into guided learning for students, teams, companies, and organizations. Together, the applications and the teaching create a productive loop: practice gives the lessons substance, and teaching brings sharper questions back into the work.
Projects
A public workbench for projects that are still moving. Each entry states what works, what does not, and what comes next.
A working native macOS planning app—and proof of product design authority before, during, and after AI-assisted implementation.
A working native macOS file-curation app—and a second proof of augmented product design with AI as an engineering collaborator.
A trilingual workflow automation for tour CO2 tracking, built in two days and preserved as a frozen proof snapshot.
Writing
Essays, notes, case studies, and practical observations on design, systems, and everyday life with AI.
DONE. is a concept mobile app built around one deliberately antiproductivity constraint: choose a single meaningful task, commit to it, finish it, and then stop.
A controlled study shows different commercial chatbots materially diverge in how they respond to users exhibiting delusional symptoms.
Sony's Ace demonstrates AI moving beyond virtual tasks into high-speed, embodied human domains.
Better systems. Better judgment. More human results.
