For a medium-sized industrial client, I developed a holistic strategy for the company-wide use of digital communication surfaces in collaboration with a digital signage software provider.

As part of a structured discovery process, I collected and prioritized internal requirements from various departments. Based on this, I developed a brand-compliant visual concept and a Screen Experience Playbook — a practice-oriented set of rules with concrete design recommendations for creating and maintaining digital signage content.

The playbook considers different display contexts such as production halls, canteens, and reception areas, and defines themes, layouts, typography, and color systems for consistent, impactful communication at the point of display.

Result: An immediately usable framework that provides clear guidelines for internal teams and external service providers — scalable and transferable to other locations.

As UX/UI Lead at Graiq, I am designing a B2B SaaS platform that helps medium-sized companies systematically access hidden knowledge — in folders, systems, and the minds of experienced employees.

The core of the platform is a company-specific knowledge model in the language of the respective industry, which makes AI statements reliable and understandable. The application is deliberately fully usable even without AI.

My area of responsibility includes the entire UX architecture, UI design, and the conception of the intake and setup process — the crucial initial phase where company knowledge is systematically captured and modeled.

– UI Design of the Penny mobile app and ongoing maintenance of the company-wide design system — carried out with a senior UI designer from the Artyspark team.

– Management, briefing, and quality control of all design decisions; close coordination with the internal Penny product team from product management and development.

– Ensuring consistent UI standards across the app and design system; review and approval of components, tokens, and guidelines.
