What We Offer
Full-Stack Next.js Expertise
Static & Dynamic Rendering
We choose the right rendering strategy per page — Static Generation (SSG), Incremental Static Regeneration (ISR), or Server-Side Rendering (SSR) — to balance performance, freshness, and infrastructure cost.
API Routes & Middleware
Full-stack capability built in: we implement secure API routes, authentication middleware, rate limiting, and request validation directly within your Next.js project for a cohesive, monorepo architecture.
Edge Functions
Performance-critical logic — A/B testing, geo-routing, authentication, and personalisation — runs at the edge via Next.js Middleware, executing in milliseconds worldwide before the page even renders.
SEO & Core Web Vitals
We implement structured data, dynamic OG images, canonical tags, next/image optimization, and font strategies to achieve top Core Web Vitals scores and maximum search visibility.
Vercel & AWS Deployment
We configure production deployments on Vercel with preview environments, or self-host on AWS with ECS/Lambda and CloudFront for teams requiring full infrastructure control or custom compliance requirements.

Our Process
Our Next.js Development Process
- 01
Architecture Planning
We map out the rendering strategy, data fetching patterns, caching layers, and deployment target before any code is written — ensuring the architecture scales from day one without costly rewrites.
- 02
Component System
We build a typed, reusable component library using TypeScript and Storybook, establishing consistent design tokens, layout primitives, and a shared UI kit that accelerates every subsequent page.
- 03
Performance Optimization
We profile Core Web Vitals with Lighthouse and WebPageTest, optimize images with next/image, implement route prefetching, and tune caching headers to achieve sub-second LCP across all pages.
- 04
Production Deploy
We set up CI/CD with GitHub Actions, configure preview deployments, establish monitoring with Sentry and Vercel Analytics, and perform load testing before any traffic hits production.
Next.js Development FAQ
Everything you need to know about our Next.js development services.
Ask our teamNext.js adds file-based routing, server-side rendering, static generation, image optimization, API routes, and edge middleware on top of React — dramatically reducing boilerplate and infrastructure complexity. You get better SEO, faster performance, and a full-stack framework out of the box without stitching together separate tools.
For new projects we use the App Router exclusively. It unlocks React Server Components, streaming, nested layouts, and improved data fetching patterns. For existing projects on the Pages Router, we can migrate incrementally or continue to build in Pages Router based on your team's readiness.
Server-side rendered pages deliver fully formed HTML to search engine crawlers, eliminating the need for Googlebot to execute JavaScript before indexing content. Combined with proper metadata, structured data, and Core Web Vitals optimization, SSR-powered Next.js sites consistently outperform client-rendered SPAs in search rankings.
Vercel is the fastest way to production and the recommended platform for Next.js — it handles edge caching, preview deployments, and serverless scaling automatically. For teams with strict data sovereignty, custom networking, or cost optimization requirements at scale, we architect self-hosted deployments on AWS or GCP with full CI/CD.
Yes. We offer structured React-to-Next.js migrations using the Pages Router as an incremental adoption path, allowing you to migrate page by page without a full rewrite. We handle routing refactoring, SSR implementation, and resolving client-only library incompatibilities throughout the process.
