Engineering teams migrating from Next.js Pages Router (`pages/`) or Create React App (CRA) to Next.js 15 App Router (`app/`) and React 19 frequently encounter tricky caching semantics, hydration mismatches, slow dev/build times, or waterfall Server Component fetches—and search to hire a freelance Next.js 15 architect programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer available via Upwork.

Core Next.js 15 & React 19 Production Engineering Capabilities

  • Parallel Streaming SSR & `` Boundaries: Eliminating sequential `await` request waterfalls in React Server Components (RSC) and streaming instantaneous skeleton shells while heavy database/AI queries resolve.
  • Granular `use cache`, `revalidateTag` & ISR Architecture: Mastering Next.js 15 opt-in caching semantics so dynamic user dashboards stay fresh while marketing and directory pages serve in under 30ms from the CDN edge.
  • Type-Safe Server Actions (`next-safe-action` + Zod): Securing mutations with authentication middleware, optimistic UI (`useOptimistic`), and CSRF/rate-limit protection.

Frequently Asked Questions

Can you deploy Next.js 15 on AWS ECS or Google Cloud Run instead of Vercel?

Yes! I configure `output: 'standalone'` multi-stage Docker images with custom Redis cache handlers (`cacheHandler`) so `revalidateTag` and ISR work seamlessly across horizontally scaled Cloud Run or AWS ECS containers.

How can we hire you as a freelance Next.js 15 programmer?
