Freelancer profile translated to English.

Description

I help from emerging SaaS startups to established companies to develop performant, maintainable, and user-centric frontends – from the first line of code to the production-ready application.

My focus is on well-thought-out UI design, efficient state management, and clean architecture. I develop UIs that not only look good but feel right – fast, stable, and scalable.

Whether it's a greenfield project or an existing app: I help teams to clearly design and implement complex form logic, data flows, and component structures.

Technical focus: React, TypeScript, form state management, Tailwind, ShadcnUI, MUI, react-testing-library – with clean code, automated tests, and an eye for detail.

If you are looking for someone who doesn't just "build" frontends but understands them – from user flow to API – then you've come to the right place.

👉 Let's talk about your project – I look forward to the exchange.
