Clinomic
Senior Product Designer, Usability Lead · 08/2025 – present · Aachen
Rebuilding mona OS, Clinomic's critical care platform, alongside the Head of Product. Anything data-intensive in acute care can be modelled on it. Whether that becomes an anaesthesia information system, a patient data management system or an emergency department solution is a matter of configuration.

Class IIa medical device
Usability to IEC 62366-1
As usability lead I own the documentation for certification. Every requirement can be traced from fieldwork into the product.
A prototype beside the product
What a canvas cannot hold, I build as a working prototype beside the product. I write parts of the front end myself.
Tested before release
Doctors and nurses test the flows formatively while they are designed. Representative users test them summatively before a release.
Safe by design
Touch targets keep their size however dense the data gets. A person's entry outranks a device value.
Information architecture before screens
Before I design screens, I map the core entities and how they relate, in collaboration with doctors and nurses.
Nothing averaged away
On a patient's timeline a coarser view never averages. It shows the last real value and marks what it hides, so nothing relevant disappears.
A blueprint for medical interfaces
I define the navigation and the floorplans for every view. Patient and allergies, for example, always sit in the same place.
From standard to interface
I design the interface by the rules of FHIR. A wrong entry is not deleted but marked as an error. That way everyone sees what happened.
Peace of mind, not blanks
Safe use starts with the users' mental models. A no has to be visible too: “No allergies” gives peace of mind, an empty field does not.
Friction that protects
In medicine, friction also means safety. Where a wrong step can do harm, I build it in on purpose.
Loud only when it counts
A screen gets loud only when the situation calls for it. Otherwise the real alarm drowns in the noise.
Complex tasks, manageable steps
What looks like one click in a hospital is often a complex task. I break it down into manageable steps. That lowers the cognitive load, and nothing gets lost.
Designed for the real workplace
Hospitals mean shared computers, gloves, switching between paper and screen, and constant interruptions. I design for that reality, not for someone in an office.
Patterns, not sprawl
Many documentation tasks look different but run the same way. I work out shared patterns and make them available. New documentation tasks build on them instead of creating new variants every time.
Design system
11 % → 76 % asked-for parts used
AI-native design system
Agents got only a basic sentence like “Build this screen” and no human help. On the first try they used 76 per cent of the required parts; without the design system, 11.
Contrast that is measured
Colour has roles, and the contrast of every pairing is measured. Status never relies on colour alone.
Many standards, one design system
A clinical product has to follow several standards at once. I bring them together in one design system. So every view is safe and easy to use from the start.
Role and team
Research in the hospital
I have been in the operating room and the ICU and watched how the work is done there.
Design team
I guide a small design team that keeps a much larger engineering team supplied with work it can build.
Directing AI agents
Much of the prototype is built by AI agents. I write the specification, review at the irreversible step and catch what they miss.
Research beyond users
Before a concept, I read what governs the work: clinical guidelines, professional agreements, safety notices and competing products, each claim labelled by how well it is sourced.
Critique before code
Developers, doctors and nurses critique a design before anyone builds it. Their objections change it while it is still cheap to change.
Setting up design practice
In my first weeks I set up the way design is done here: principles, critique format, personas, and usability engineering inside the regulated process.
Specs that cannot drift
A design reaches engineering as a ticket with its reasons and testable behaviour, and its reference page is frozen so picture and requirement cannot drift apart.
A studio for design work
I built a design studio that holds complex design work as data: open questions, decisions and the tests that settle them. Agents work in it over an MCP server.
