Hire Next.js Developers
Your product team has a roadmap full of features, but your front-end bench is stretched thin. We plug senior Next.js engineers directly into your sprint cadence—developers who already ship production code with the App Router, React Server Components, incremental static regeneration, and Vercel deployment pipelines.
Every engineer we place has delivered at least two production Next.js projects. They join your standups, follow your PR conventions, and push code to your repo—not ours. Whether you need one mid-level developer for three months or a squad of three seniors for a platform rebuild, we scale around your priorities without the overhead of a traditional agency engagement.
- Average ramp-up: 7 business days from signed profile to first merged pull request.
- Expertise across App Router, Pages Router, ISR, middleware, edge functions, and Vercel CI/CD.
- Pair with our React or TypeScript specialists for broader squad coverage.
What our Next.js engineers actually do
They don't just "know React"—they ship production Next.js every week.
The gap between "React developer" and "Next.js developer" is wider than most hiring managers expect. A strong Next.js engineer thinks in terms of rendering strategies—when to stream a Server Component, when to defer to the client, when ISR is the right trade-off for a product catalog with 50,000 SKUs. They also own the deployment story: preview environments, edge middleware for A/B tests, image optimization budgets, and Core Web Vitals monitoring in production.
Here's the practical breakdown of what our engineers bring to your codebase from day one:
App Router & Server Components
Our engineers build layouts, loading states, and error boundaries using the App Router's nested architecture. They use Server Components to cut client-side JavaScript, stream data-heavy pages, and co-locate data fetching with the UI that renders it. For teams still on the Pages Router, they lead incremental migrations without disrupting live traffic.
Data Fetching & Caching
ISR, on-demand revalidation, React cache(), and fetch() with revalidation tags—our developers pick the right caching pattern for each route and explain the trade-offs to your product team. They've shipped storefronts that serve 200k+ pages from edge caches while keeping inventory data fresh within 60 seconds.
API Routes & Full-Stack Patterns
Route Handlers, Server Actions, middleware chains, and edge functions—we treat Next.js as a full-stack framework. Our engineers connect to Postgres via Prisma, wire up Stripe webhooks, handle NextAuth/Clerk session management, and set up rate-limiting middleware. Need a deeper backend layer? They pair smoothly with our Node.js specialists.
Performance & Core Web Vitals
Largest Contentful Paint, Cumulative Layout Shift, Interaction to Next Paint—these aren't buzzwords, they're shipping criteria. Our developers use next/image with responsive breakpoints, next/font for zero-layout-shift typography, dynamic imports for heavy client modules, and Vercel Speed Insights or custom Datadog dashboards to track real-user metrics after every deploy.
Testing & CI/CD
Every feature ships with tests. Our engineers write component tests with React Testing Library, integration tests with Playwright or Cypress, and visual regression snapshots with Chromatic. They configure GitHub Actions or Vercel CI pipelines with Lighthouse CI gates so performance regressions never reach production quietly.
Design System Integration
Tailwind CSS, Radix UI, shadcn/ui, Chakra, or your own component library—our developers slot into whatever design system your team uses. They build accessible, responsive layouts and work closely with designers to bridge Figma specs and production code. Need cross-framework consistency? Pair them with our Vue.js team.
Why teams choose Next.js right now
It's the default React framework—and the reason matters for hiring.
When the React documentation itself recommends Next.js as the starting point for new projects, that tells you something about where the ecosystem is heading. Server Components, streaming HTML, and edge rendering aren't experimental—they're the production default for companies like Notion, Hulu, and Target. Hiring developers who already operate in this paradigm means your team avoids a costly learning curve.
SEO that actually works
Server-rendered pages and static generation mean Googlebot sees fully rendered HTML—not a blank <div id="root">. Metadata API, JSON-LD helpers, and dynamic OG images make technical SEO a first-class concern rather than an afterthought bolted on with a third-party library.
One codebase, full stack
Route Handlers replace the need for a standalone Express or Fastify server for many use cases. Authentication, form processing, database queries, and webhook handlers live alongside the UI. That's fewer repos, fewer deploys, and a simpler mental model for the whole team.
Built-in performance budget
Automatic code splitting, the next/image loader, font subsetting, and Vercel's edge network give you sub-second Time to First Byte without custom CDN configs. Our engineers layer Lighthouse CI into your pipeline so regressions get caught before they hit users.
Deployment flexibility
While Vercel is the most common target, Next.js runs on AWS (via SST or OpenNext), Google Cloud Run, Docker containers, and self-hosted Node servers. Our developers have deployed across all of these and know the trade-offs of each.
Why our preferred stack is React + Next.js + Node.js on Vercel
Fast delivery, strong DX, and production-grade performance.
For modern web products, this stack gives teams the right balance between speed and long-term maintainability. React handles UI composition, Next.js adds SSR/ISR and routing conventions, Node.js powers API workloads, and Vercel simplifies preview environments and continuous delivery.
There is also a strong Argentine connection to this ecosystem: Guillermo Rauch, the creator of Next.js and CEO of Vercel, is originally from Lanus, Buenos Aires (source). Our Argentina-based engineers are deeply active in this community and bring practical experience shipping React/Next/Node applications to Vercel at scale.

Case study: Rebuilding a SaaS dashboard with Next.js 14
How two augmented engineers cut page load times by 64% and unblocked a stalled product launch.
Client: A B2B analytics company with 3,000+ enterprise accounts. Their React SPA dashboard—built with Create React App three years earlier—had grown to 2.8 MB of client JavaScript, Lighthouse scores below 40, and chronic hydration mismatches that broke saved filter URLs shared between teammates.
What we did: We embedded two senior Next.js engineers alongside the client's three in-house front-end developers. Over twelve weeks the augmented squad:
- Migrated 47 routes from CRA to the Next.js App Router, converting data-fetching logic to Server Components and eliminating 1.9 MB of client-side JavaScript.
- Introduced ISR with on-demand revalidation for report pages, dropping average Time to First Byte from 3.2s to 380ms for cached routes.
- Implemented Playwright integration tests for the top 15 user flows and added Lighthouse CI gates to the Vercel preview pipeline.
- Rebuilt the charting layer with lazy-loaded
next/dynamicimports, cutting Interaction to Next Paint by 52%.
Result: Lighthouse performance score climbed from 38 to 91. The product launched on schedule, customer-reported "slow dashboard" tickets dropped 78% in the first month, and the client's CTO promoted two of their in-house developers who leveled up through pairing with our engineers.
Key metrics
- 64% faster average page load (3.2s → 1.15s real-user P75).
- 1.9 MB of client JS removed by migrating to Server Components.
- 91 Lighthouse performance score (up from 38).
- 78% reduction in "slow dashboard" support tickets.
- 12 weeks from kickoff to production launch.

How augmentation works
From signed profile to merged PR in under two weeks.
- Scope & match: You share the tech stack (App Router vs. Pages Router, TypeScript version, styling approach, CI tool) and the seniority level you need. We shortlist 2-3 engineers who shipped in a similar context.
- Technical interviews: You interview the candidates—pair programming, system design, or whatever your hiring bar looks like. You have final say on every engineer.
- Onboarding sprint: The first week focuses on repo access, environment setup, codebase walkthroughs, and a small starter ticket that proves the merge-to-deploy flow works.
- Embedded delivery: Engineers attend your ceremonies, follow your coding standards, and push to your repos. Expect weekly async updates and monthly skill-gap reports.
- Scale or transition: Add engineers when the roadmap demands it, or wind down with a structured handover—ADRs, Loom walkthroughs, and documented conventions your internal team inherits.
