Sara Schönherr
Last position:
Senior Software Developer with a Focus on UI/UX at vGen GmbH
Development of an interactive prototype for the concept of an AI-supported Enterprise Architecture Management tool. The goal was to present complex relationships between IT systems, business processes, and departments in a way that is easy to understand and to support decision-making in the context of IT transformations.
The prototype combined data-driven analyses with guided questions and interactive visualizations. A central part was the integration of a RAG process to provide domain-specific EAM knowledge in context. The focus was on quick idea validation, user-centered interaction design, and the technical feasibility of a scalable overall concept.

About the technology
Interface work
UI Design shapes how people see and use a product. It covers screens, states, navigation, forms, feedback, and visual hierarchy. Strong work makes software easier to understand, faster to use, and more consistent across the product.
Common deliverables
- Web and app screen designs
- Design systems and component sets
- Interactive prototypes
- Responsive layouts for different devices
- Handoff assets and UI specs
Tools and handoff
Most UI design work happens in Figma, Sketch, or similar tools. Specialists also prepare component libraries, style guides, and clear notes for development teams. Good handoff reduces guesswork and keeps the final product close to the approved design.
When companies bring help
Teams usually look for freelance expertise when a product needs a refresh, a new feature set, or faster design capacity. The same applies when an internal team needs support on a design system, usability cleanup, or a tight release in Cologne or with remote product teams.
What strong specialists do
Strong UI Design professionals think in flows, not just single screens. They align visual choices with product goals, keep states and edge cases clear, and work well with product, content, and development specialists. They also respect accessibility, consistency, and real implementation limits.
Cologne project fit
Cologne companies often need UI design for B2B software, e-commerce, media products, and internal tools. Local teams may want on-site workshops, while many execution tasks work well remotely. In both cases, clear communication and quick feedback cycles matter more than location alone.
Frequently asked questions
What clients ask us most about UI Design — answered in short.
UI Design covers the visual and interactive layer of a digital product. That includes layouts, navigation, states, form patterns, buttons, and the way content is presented across screens. The goal is a clear interface that is easy to scan and simple to use.
UI Design focuses on what people see and interact with on the screen, while UX design looks at the overall journey and structure. In practice, the two overlap, but UI specialists pay closer attention to visual hierarchy, spacing, components, and consistency. Companies often need both, but not always in the same person.
A strong UI Design freelancer should be comfortable in Figma and understand how to work with component libraries, design tokens, and prototype flows. Sketch and Adobe XD can still matter in some teams, but Figma is the most common day-to-day tool. They should also know how to hand off clean specs to development specialists.
UI Design is often needed for new products, redesigns, feature expansions, and design system work. It also comes up when a company wants to clean up a cluttered interface, improve mobile usability, or make a complex workflow easier to follow. B2B software and e-commerce products are common examples.
The right UI Design specialist depends on the task. A small screen refresh may only need someone who can move fast and stay consistent, while a design system or product overhaul needs someone who can handle structure, states, and handoff carefully. The key is proven work on similar interfaces, not a job title.
Yes, UI Design work is often well suited to remote collaboration. Many Cologne teams prefer a mix of remote delivery and live workshops for feedback, especially when product, content, and development specialists are in different places. On-site time helps when a project starts with discovery or alignment sessions.
Look for clear before-and-after thinking, not just attractive screens. A strong UI Design portfolio shows structure, consistency, real product flows, and attention to edge cases such as empty states, errors, and different screen sizes. It should also show how the work fits the product, not only the visual style.
Useful adjacent skills include UX thinking, accessibility awareness, information architecture, and basic front-end understanding. UI Design specialists who can read component behavior and understand implementation limits usually collaborate better with product teams. Copywriting and content design also help when interfaces need clearer labels and messages.
