I help founders turn their MVP into a product investors and users trust.
One person for design, development, and product. No handoffs. I build websites, mobile apps, and internal business applications in React, Next.js, and TypeScript. I own analytics, experiments, and product decisions. Currently based in Düsseldorf.
Interface, code, and the data checks behind it: no handoff between them, because one person does all three. I was a B2B product owner and BI analyst at Rewe Group and a data scientist at Infas360. So I know product and data from the inside, and I build the interface and the code myself. Software architecture, UI in Figma, Python and SQL pipelines: one person owns every layer, so the system holds up as usage and complexity grow.

I design and build the frontend myself. What you see in Figma is what ships, no AI-vibecoded product that only works on the surface. Most projects lose quality right at the handoff between design and development: details get simplified, interactions get cut. I think about code and scalability from the first design decision, so changes are faster to make later. You get one point of contact instead of two invoices. If you already have a backend team, I plug straight into your existing setup.
I look at where you’re at and find the spots that make you look bad in front of investors or users. An MVP proves the idea works. Your next funding round needs a product that’s just as convincing. I work outward from the weak points, toward a UI with no rough edges and an architecture that can carry your next stage of growth.
I understand product decisions, UI details, and data infrastructure as one connected picture, a combination that makes handing off to more specialists unnecessary. Right now I work with React, TypeScript, Astro, and Next.js. That’s the stack running through my projects. On top of that: two years as a B2B product owner at Rewe Group, plus data analysis work at Infas360 using Python and SQL. That combination is exactly why nothing gets lost between design, code, and data when you work with me.
Every project starts with a call to define the scope. After that, you get a fixed price for that scope, so you know the total cost before any work begins. If the scope changes, I send you an updated quote first.
Most projects run 8 to 12 weeks, depending on scope. A landing page moves faster than a full product build. You’ll get a realistic timeline for your project during the scoping call.
The process runs in clear stages: discovery call, UX research and wireframes, development and testing, launch. In the discovery call, I get to know your product and your goals. I usually skip high fidelity prototypes, that time is better spent building the real thing. So from wireframes, I move straight into building. You review and sign off on every stage, so nothing catches you off guard at the end.
If you’re looking for an agency with a big team and multiple points of contact, I’m not the right fit. Same goes if your project is mostly backend or infrastructure work with little to no UI. Looking for a full time hire for your core team instead? That’s a different need. I work project based, as a contractor, not as part of your team. I’m the best fit for founders with a clearly scoped project who want design and frontend handled by one person, with clear ownership in one place.
You show me where your product stands. I’ll tell you straight whether and how I can help. Anything under NDA, we cover on the call.
