I translate complexity into usable products.

A research product people can trust needs more than powerful AI. It needs reliable sources, transparency and traceability. Elyvite helps health professionals stay up to date and research complex topics. It shows where leading experts agree, where they disagree and how that compares with current studies.

• Product strategy, UX and interaction design
• Full-stack development, AI agents and multi-model orchestration
• Research and knowledge architecture across three layers: expert knowledge, studies, web
• SaaS operations with authentication, billing and six languages
• AI transparency and the requirements of the EU AI Act

Today Elyvite is a live SaaS product, available internationally, with subscription billing and fully in production.

Building software with AI becomes far more powerful when AI is part of a structured development process rather than just a coding assistant. Together with my co-founder I am building makerOS: visual product planning, specialised AI agents and development tools in one connected workflow.

• Product strategy and UX for an AI-native development environment
• Workflows that connect product planning and software development
• Specialised AI agents for different development tasks
• Kanban and visual planning for human and agent collaboration

We build our own products with the platform. That makes it both a development environment and a continuous real-world test.

From idea to a live product in three months. I designed, built and launched GrappleKit: from concept and UX to native iOS development, AI infrastructure and App Store release.

• Product strategy, concept and UX/UI
• Native iOS development, backend with Supabase
• AI-powered search across 40,000 training videos from 44 curated channels
• Video library, training journal, technique tracking and a coach dashboard

The project changed how I think about product design: when you have to build and run your own product, an additional option is no longer just an element but logic, states, tests and maintenance.

What should business banking look like in 2030? As part of a multidisciplinary team I worked on the Vision 2030 Playbook for DKB private and business banking, looking at how changing customer needs and emerging technologies will shape the digital banking experience.

• Exploring future customer needs, scenarios and digital experiences
• Translating strategic ideas into tangible UX/UI concepts
• Developing user journeys and interaction concepts
• Making future banking experiences visible through design

The result was a shared, tangible vision that makes possible directions for business banking easier to explore, discuss and develop further.

A mission-critical digital workplace used every day by more than 30,000 train staff across Germany. The task was to turn complex, time-critical railway operations into an experience that holds up in real conditions: on the move, under time pressure and across different roles.

• Leading UX across multiple development teams
• Information architecture, interaction concept and interface
• Consistent patterns across a growing set of features
• Close collaboration with product owners, business analysts, developers and the DB brand team

The result is a unified digital workplace for one of the most demanding environments there is: thousands of people making time-critical decisions while the trains are moving.

Designing a product for more than ten years changes how you see UX. As a long-term design partner and UX lead I shaped mHub, a modular MES and IIoT platform for complex industrial production. It connects the shop floor with business operations: processes, machines and real-time data in one system.

• Designing the platform and its modular ecosystem
• Translating complex manufacturing processes into usable workflows
• Information architecture for data-heavy applications
• Designing for very different roles, from the shop floor to production planning
• Prototyping and validating new product concepts

My designs run in real production environments, including at ZEISS, Fraunhofer, Yokogawa, Agathon, Allgaier and voestalpine. The biggest lesson from ten years: enterprise UX is rarely about simplifying everything. It is about understanding the domain well enough to know which complexity can go and which has to stay.

How do you make complex disruption information understandable when passengers need it most? The task was not to redesign notifications, but to determine which information matters, how it should be structured and prioritised, and how different disruption scenarios can be communicated consistently without overwhelming anyone.

• Leading the UX concept and interaction design
• Translating complex disruption scenarios into clear information structures
• Exploring approaches through rapid prototyping and testing them with users

The work ran through several design and research cycles in which the concept was tested with real passengers and refined from findings and feedback.

Production software has to turn operational data into information people can understand and act on. I worked on a time tracking and reporting application for a production environment, translating processes and data into a clear, efficient interface.

• UX/UI for production workflows
• Time tracking and reporting views
• Information architecture and user flows
• Structuring data-heavy interfaces and reports

Another piece of experience with B2B applications where complex processes and operational data have to become simple tools for everyday work.

Consistency across a large and growing ecosystem of digital products does not come from designing individual interfaces. Together with the Deutsche Bahn design team I developed standards and reusable patterns for the group's digital products.

• UX and UI standards for recurring interaction patterns
• Reusable patterns and guidelines across products
• Translating brand principles into practical design rules
• Foundations that different product and design teams can apply consistently

The work paved the way for a more systematic approach to product design: fewer inconsistencies between products and a shared foundation for new experiences.

Modernising a legacy platform means knowing what to change and what to preserve. I led the redesign of Deutsche Bahn's existing information platform, from analysis through implementation. Existing workflows, functionality and user expectations had to be understood and kept while the platform was renewed both in UX and in technology.

• Identifying usability issues and opportunities in the existing platform
• Simplifying and restructuring established workflows
• UX concepts and prototypes for the new experience
• Validating and refining concepts through extensive user testing

The result was a modernised platform that keeps what users rely on while being clearly easier to use.

Making everyday activity more engaging through social interaction and friendly competition: that was the task. I developed the UX concept for a new version of Social Steps, an iOS app that lets users create and join activity challenges with friends and colleagues.

• UX concept and information architecture
• User flows and interaction design
• Challenge and competition mechanics
• Prototyping the core app experiences

The project added a consumer perspective to my work: usability combined with motivation, social interaction and the wish to come back.

As UX Design Lead I supported ODDSET on mobile, on the web and at the terminal, aiming for a consistent, intuitive experience on every platform. A part-time partnership until the team had filled a permanent design role.

• UX support across the three product lines
• Consistent experiences across all platforms
• Handover to the in-house design team

As UX Design Lead I helped the team visualise its vision for the Major Disruption Assistant and validate it through testing with real users.

• Translating the team's vision into a tangible prototype
• Validation with real users

A tangible vision for the future of a B2B marketplace in the chemical industry. As part of a multidisciplinary team I developed the design vision for the marketplace, translating the requirements of a complex, highly specialised B2B environment into a modern digital product experience.

• Overarching UX/UI design vision
• Exploring the future product experience and interaction model
• Information architecture and key user journeys
• Representative screens and prototypes of the key moments

The result was a product vision that made the future marketplace experience visible, discussable and actionable for stakeholders and product teams.

Turning a new product idea into a mobile experience users understand immediately. I was responsible for the UX concept of a new app that connects electric vehicle charging with a rewards ecosystem, translating the business model from an early-stage idea into a clear user experience.

• Leading the UX process from early concept to product experience
• Planning and facilitating a design sprint to align product, business and user needs
• Information architecture, user flows and interaction concepts
• Building and iterating prototypes

The project turned an early-stage idea into a structured product experience and laid the UX foundation for the &Charge app.

How do passengers interact with a self-driving taxi? For an autonomous mobility concept I worked on a prototype for the in-car experience: how passengers use digital services inside the vehicle and how the interface supports a simple, comfortable journey.

• UX/UI of the in-car application
• Interaction concepts for autonomous mobility
• User flows and interface design
• Prototyping the key passenger interactions

A premium digital service needs a consistent experience at every touchpoint. For Porsche Digital I worked on a concierge service, both the native iOS app and its companion product website, translating the service into a clear, intuitive experience that lives up to the brand.

• UX and UI of the iOS application
• User flows and interaction design
• UX/UI of the product website
• A consistent experience across app and web
• Translating the premium brand's standards into digital interactions

Before it evolved into the new DB Navigator, Vendo was Deutsche Bahn's initiative to rethink the digital travel experience on mobile platforms. I worked on the mobile product experience for iOS and Android, helping shape how passengers interact with the railway's digital services.

• UX/UI for iOS and Android
• Mobile interaction patterns and user flows
• Translating complex travel and mobility requirements into intuitive interfaces
• Consistent experiences across both platforms

Another perspective on mobility: customer-facing experiences for one of Germany's most widely used digital service environments.

With Binder Consulting I worked on the software that evolved into COLMEIA, a platform for managing complex global job structures and workforce data. My task was to translate complex HR processes, organisational structures and large amounts of data into a clear, usable enterprise product.

• Interaction and visual design of the software
• Translating complex HR processes into clear digital workflows
• Information architecture for data-heavy enterprise applications
• The platform's visual language and reusable UI patterns

A good example of the work that shaped my approach: understanding a complex domain deeply enough to turn it into something people can actually use.

Designing a digital betting experience across desktop and mobile means translating complex betting mechanics into interactions users understand quickly. As part of the ODDSET UX team I worked on a new sports betting platform for the German market.

• UX concepts for desktop and mobile
• Information architecture and user flows
• Interaction design for complex betting journeys
• Wireframes and prototypes
• Consistent experiences across screen sizes and contexts

Early experience with complex transactional products across platforms. Five years later I returned to ODDSET as UX Design Lead.

Secure cloud storage has to make powerful security features accessible without making the product feel complex. I worked on the product experience of DRACOON, a secure cloud storage solution for professional and enterprise environments, translating the requirements of a security-focused product into a clear user experience.

• UX/UI of the cloud storage platform
• Information architecture and user flows
• Simplifying technically driven functionality for end users
• Wireframes, interface concepts and prototypes

The project strengthened my experience with B2B software where usability, technical complexity and security requirements have to work together.

In 2012 I co-founded Shopbezirk, one of Europe's first online shops dedicated entirely to vegan dog food and accessories. What started as a small WooCommerce store quickly grew into a real e-commerce business: demand and product range grew so fast that we moved into our first warehouse and rethought the technical foundation, migrating from WooCommerce to Shopware.

• Building and evolving the e-commerce platform
• UX and customer experience
• Product sourcing, including imports from the US
• Marketing and customer acquisition
• Operations, logistics and fulfilment

After several years of building and scaling, we sold the business. What stayed with me: building a digital product is far more than the interface. Technology, operations, customer needs and business decisions are all part of one system.

In 2008 I founded kopfbezirk, my first design agency, working for clients from established enterprises to mid-sized production companies. Over six years I led creative and digital projects for clients including KPMG, Allianz and Ratpack Filmproduktion, combining design, emerging digital technologies and strategic communication.

• Digital and interactive experiences
• Early mobile applications, web design and development
• Brand and communication design
• Film and media production
• Client consulting and project leadership

As founder my role went far beyond design: acquiring and advising clients, developing concepts, leading projects and bringing the right people together. This is where I learned to see design not as an isolated discipline but as part of a larger business and product context.
