Product Engineer · Berlin

Ideas only become useful when they work.

I build web products from the first sketch to operations: technically sound, understandable and aimed at a real outcome.

02 / Approach

How I work

Not every problem needs a new framework. But every problem needs a clear decision.

From concept to MVP

Understand the problem, cut the scope, build the first useful step. Fast enough to learn, clean enough to continue.

Full-stack delivery

Frontend, backend, data model and deployment from one hand — with TypeScript, web standards and an eye for operations.

Evolution & partnership

Take over existing products, reduce technical debt and support teams without slowing them down.

04 / About

Technology is craft. Products are decisions.

I have been building web products for more than ten years — first as a developer, now as a product engineer. I care about how code becomes something people actually use.
