About

Senior Frontend Developer with a designer's eye and a builder's mindset. Over the past 20years, I've turned complex problems into intuitive interfaces. Driven by curiosity, creativity, and a love for tech that actually helps people.

For 10+ years, I've freelanced across industries, shipping over 30 projects from MVPs to production-ready apps. Today, I focus on crafting fast, elegant software that balances aesthetics with performance.

Whether working solo or co-founding products like ellume, my goal stays the same: Build things that matter. Bridge the gap between what is and what could be.

Frequently Asked Questions

What frontend technologies do you specialize in?

I specialize in React.js, TypeScript, Next.js, Expo and React Native for mobile development. I also work extensively with modern CSS frameworks like TailwindCSS and have deep experience with JavaScript ES6+ and component-based architecture.

Do you work with clients remotely?

Yes, I work with clients both locally in Germany and remotely worldwide. I'm based in Heilbronn, Germany, but most of my freelance projects are conducted remotely with excellent communication and project management systems.

How long does a typical web development project take?

Project timelines vary based on complexity. I provide detailed project estimates during our initial consultation.

Can you help with existing React applications?

Absolutely! I frequently help clients optimize existing React codebases, migrate from older technologies, implement new features, fix performance issues, and modernize legacy JavaScript applications to TypeScript.
