Designing based on data, not feelings
Whenever possible, I always work on the basis of facts – access statistics, user tests, interviews with users and stakeholders... In this way, all team members have a common understanding of requirements and goals without being completely dependent on personal feelings and assumptions. Especially with existing products it is easier and cheaper than ever to collect significant data.
Product development must be iterative
A digital product is never finished. On one hand, because technical development is so fast, on the other hand, because with each release new insights into users and usage can and must be gathered. The analysis of this data starts a new iteration loop and allows an improvement. Often it becomes really interesting only at the second round, because often only then you have the necessary data. Therefore I prefer a long-term cooperation with my clients.
Release faster, learn faster
I am a proponent of several smaller releases instead of one big one. Not only because users get new functions faster and get the feeling that the product is being taken care of. It's also because you gain new insights more quickly. I'm also a fan of the MVP concept.
Deep understanding of technical development
Since I also work as a frontend developer (on a small scale), I have a good, always up-to-date understanding of development processes. This enables me not only to communicate with developers, but also to realize a cost effective design process and implement hi-fi prototypes.
Focus on function with an eye for aesthetics
The most beautiful visual design is useless if the product is not understood. Nevertheless, a really good user experience also needs the appropriate visual appearance. Even though my focus is on conceptual design, I have many years of experience as a UI designer. Furthermore, I often work closely with art directors, UI and communication designers.

Projekthistorie
• Long-standing, ongoing collaboration as UX and UI designer for the Berlin-based fintech startup, including evaluation of usability tests.
• Supported two website relaunches, including delivery of CSS specs and QA.
• Built a design system in Figma.
• Focus on the web app: the application flow (funnel/wizard) and the internal area for managing investments.
• Joined as the first hire after the three founders; by the end of the engagement the company had grown to over 80 employees.
• Built the “Parcel Shuttle” MVP from the ground up: wireframes, designs, and web frontend.
• Developed a highly complex driver app for tablets and smartphones from scratch (supporting parcel delivery) – from wireframes through MVP to final UI, including live test drives with drivers in the field.
• Back-office web application for managing app users and licenses – also taken through wireframes → MVP → final UI design.
• Both the app and back office were pure B2B projects.
