I research, design and build software for people who are not experts.
Now
Oct 2026
- Building Levelwork full time with Michael Gajda. Constat shows how work is really distributed in an organisation, one structured conversation per role. levelwork.ai ↗
- Working on AI meeting minutes, now in pilot at a district administration (freelance, for gyv).
- Built Notenprogramm in nine days: choir sheet-music PDFs become editable scores and a practice MP3 for my own voice.
Selected work
- 2026–Co-founder. Building Constat with Michael Gajda.Case →
Constat sets the week a role is meant to have against the week it actually has. A deviation is not a verdict, it is a finding.
- 2026UX research and the minutes editor for the Landratsamt Konstanz.Case →
Recordings of council meetings become minutes: uncertain passages are flagged for review, and each contribution is kept verbatim, put into indirect speech or left out.
- 2026Walk while you work: a walking-pad companion for the Mac, built with Claude Code.Case →
Fed up with the remote and wanting a record of every office walk: a Mac app with keyboard shortcuts that sends each walk to Apple Health and sets goals like once around Lake Constance.
- 2026Choir sheet-music PDFs become editable scores and a practice MP3 for my voice. Built in nine days with Claude Code.Case →
Two independent music readers check each other, so only the uncertain notes of my own voice need a look. Tested on seven pieces from the Renaissance to today, with 109 automated tests.
- 2026Voice food logger, team of four. Co-built the pipeline, tests and web UI.Case →
Two LLM steps around a vector search of 1.88 million food entries. In testing, confident matches rose from 12 % to 71 %.
- 2022–25From a math-only research tool to a public web app.Case →
Designed the app around the simulation maths, one page per function, plus UI and brand. Led up to four student developers.
- 2024A design sprint that changed the lab’s direction.Case →
Turned the lab’s planned setup simulator towards how the devices are used and by whom. The finding: how often people fetch the data on their phones matters most, because network access uses the most energy.
- 2022–24Lead UX for goconut’s web app and its design system, still in use.Case →
The whole design rests on one colour in different steps, with translucent layers on top. The aim: transparency about what is going on in the office.
- 2022Master’s thesis on interacting with connected systems.Case →
A speculative office for 2045: an AI hands out the day’s appointments as blocks, a cup signals that you are open for a chat.
- 2021Exhibition on living with epidemics, built by about 80 students. Co-led the UX team.Case →
Shaped the iPad visitor guide through AR stations, historical documents and interactive infographics, and took the exhibition photographs.
