Frequently asked questions
What does working together cost?
My day rate sits in the DACH senior UX bracket. Concrete numbers on request — depends on whether strategy + concept + prototyping are needed as a package, or only one phase. UX audits are offered as fixed-price packages; longer engagements are billed by day rate × estimated effort. First conversation (30 minutes) is free.
When is an external UX designer actually needed?
When there's an idea on the table but it's unclear whether it should become a dashboard, a table, or a wizard. When teams are stuck arguing about a concept and nobody knows who's right. When a product needs to be investor-ready or hire-ready before staffing up internally. When BITV or accessibility compliance is required and no in-house expertise exists.
How long does a typical project take?
UX audit: max. 1 week of analysis + 1 week for findings and concrete recommendations. Prototype: max. 1 week, depending on complexity — a simple idea can land as a clickable prototype in a single day. Full UX strategy for a new product: 4–8 weeks. Longer engagements (3–12 months) for ongoing product development are also possible.
What comes out at the end?
Depending on the engagement and by agreement: clickable Figma prototypes, detailed findings reports with prioritized recommendations, design system components, user flow diagrams, research syntheses. All in formats developers and stakeholders can use directly — no "design wall-art," but material that moves into the roadmap and into code.
How does AI fit into the work, concretely?
AI is used throughout the design process: for research synthesis (clustering interview transcripts), for code-assisted prototyping (HTML/CSS generated directly), for iteration (three variants in the time previously needed for one). Every decision still goes through human judgment. For sensitive company data, a locally-run LLM on my own machine is also an option — so no internal data leaves the client's network.
Do you cover public-sector projects and BITV 2.0 requirements?
Yes. I've led multiple engagements in digital identity and government online services — from concept through design review to conformance testing. BITV 2.0 is the legal baseline, EN 301 549 the technical standard. I know the process from years of practice and can anchor accessibility in the design from day one, rather than retrofitting it at the end.
How does the collaboration work practically — contracts, remote, NDA?
Collaboration: Remote-first, with on-site phases for workshops, kick-offs, and complex stakeholder sessions. Day-to-day via Figma, Slack/Teams, video calls. Contracts: For startups and product teams, directly on a freelance basis. For enterprise clients that require it, via temporary employment contracts (Arbeitnehmerüberlassung, ANÜ) through personnel service providers. NDA & IP: NDAs are standard. All IP from the engagement stays with the client.
