01
App Router and Server Components
Layouts, streaming and Suspense boundaries placed deliberately, with client components kept at the leaves that need interactivity.
Senior / Principal
Hire senior Next.js developers and architects
Next.js engineers who design around the App Router's rendering and caching model — static where possible, streamed where not — and who can self-host when Vercel isn't an option.
Role profile
What we look for in a Senior Next.js Developer
Seniority and experience are agreed in the proposal, and you interview every engineer before they start. These are the skills that interview should test.
02
Caching and revalidation
A working model of the data cache, revalidateTag and static generation — and the habit of checking what each route actually does at build time.
03
Server Actions and type safety
Mutations as typed Server Actions, with input validated at the boundary and optimistic UI where it genuinely helps.

FAQ
Questions about hiring a Senior Next.js Developer
Answered the way we would on a call. If yours isn’t here, send it — we reply within one business day.
Yes. Next.js builds a standalone server that runs in a container, so it deploys to ECS Fargate, EKS or Cloud Run like any other service. The engineer will also cover what needs extra work once you run more than one instance — a shared cache for ISR and revalidation, and image optimization on your own compute.
No, and be wary of anyone who does. Lab scores swing between runs and devices. We measure field Core Web Vitals — LCP, INP and CLS from real users — before and after the work, and agree the targets with you up front.
