React to Next.js Migration Specialist in Austria
Migrate legacy React SPAs (Create React App / Vite) to modern Next.js 16 App Router for instantaneous SEO indexation, zero layout shift, and enterprise edge speed.
Why Traditional Builds Stall Growth in Austria
Client-rendered Single Page Applications (SPAs) are invisible to social crawlers and severely penalized by Google's mobile indexing bots. Austrian startups often hit a growth ceiling because client-side JavaScript waterfalls stall initial render times.
Code-Level Precision & Verified High Performance
I architect smooth, zero-downtime migrations from legacy React (CRA, Vite, Webpack) to Next.js 16. We transition your state management, decouple client-only hooks into React Server Components (RSC), preserve your existing UI components, and unlock server-side dynamic OG images and XML sitemaps.

Got Questions? Clear Answers for Austrian Clients.
Can we migrate our React app without halting current product development in Austria?
Yes. We can adopt a phased migration strategy where new features and marketing routes are built in Next.js while legacy routes are reverse-proxied until fully ported.
Will all our existing UI components work in Next.js?
Yes. Your Tailwind, Radix UI, shadcn/ui, or styled-components will be preserved while optimizing client/server boundaries with 'use client' directives.
