Next.js Development Services
Build lightning-fast, SEO-first web applications with Next.js 14/15 — App Router, React Server Components, ISR, edge rendering and Cloudflare CDN — out of the box.
Next.js 14/15 — App Router & Server Components
The App Router and React Server Components represent the largest shift in Next.js since its initial release. We are fluent in both the Pages Router (for migrations) and the App Router (for new builds) — and we know which patterns cause hydration issues, waterfall fetches and cache stale problems in production.
Next.js 14/15 — App Router & Server Components
The App Router and React Server Components represent the largest shift in Next.js since its initial release. We are fluent in both the Pages Router (for migrations) and the App Router (for new builds) — and we know which patterns cause hydration issues, waterfall fetches and cache stale problems in production.
- App Router with layouts, loading and error boundaries per route segment
- React Server Components for zero-JS server-rendered data-fetching components
- Server Actions for form submissions without separate API routes
- Parallel routes and intercepting routes for modal and nested layout patterns
- Streaming SSR with Suspense for progressive page hydration
- TypeScript strict mode across all route handlers and component files
Data Fetching, Caching & ISR
Next.js 14 unifies data fetching through the fetch API with built-in caching semantics — force-cache for static, no-store for dynamic, revalidate for ISR. We design caching strategies that keep TTFB low without serving stale content to users who need fresh data.
- Static generation (SSG) for pages that change infrequently
- Incremental Static Regeneration (ISR) with time-based and on-demand revalidation
- Dynamic rendering (SSR) for personalised, real-time content
- CMS revalidation webhooks: Sanity, Contentful, Strapi on-publish triggers
- Unstable_cache for server-side data memoisation across request boundaries
- Database query optimisation: N+1 elimination, query batching with DataLoader
Edge Runtime & Global Performance
Next.js’s Edge Runtime lets you run middleware and route handlers at Cloudflare’s or Vercel’s global edge network — geolocation, A/B testing, authentication checks and redirects executed in under 1 ms, close to your user. We design the routing layer to push as much as possible to the edge.
- Edge Middleware for auth token validation, geo-routing and A/B flags
- Cloudflare Workers deployment for teams outside the Vercel ecosystem
- next/image optimisation pipeline with format negotiation and lazy-load
- next/font for zero-CLS Google Fonts with preloading
- Script strategy management: beforeInteractive, afterInteractive, lazyOnload
- Core Web Vitals targets: LCP under 1.5 s, CLS under 0.05, INP under 200 ms
API Routes, Route Handlers & Full-Stack Capabilities
Next.js route handlers eliminate the need for a separate Express/Fastify server for many projects. We use them for webhook receivers, API endpoints, server-sent events and proxy layers — with proper streaming, error handling and rate-limiting middleware.
- Route handlers for REST and streaming endpoints
- Server-Sent Events (SSE) for real-time push without WebSockets
- Webhook receivers with HMAC signature verification
- Rate limiting middleware with Upstash Redis or Vercel Edge Config
- Prisma or Drizzle ORM for type-safe database queries from route handlers
- Auth.js (NextAuth v5) for session management across App Router pages
Deployment, Monitoring & SEO
We deploy Next.js to Vercel for the tightest platform integration, Cloudflare Pages for global edge and AWS App Runner / ECS for teams that need custom infrastructure. Every deployment includes sitemap generation, robots.txt configuration and structured data validation.
- Vercel deployment with preview-per-PR and production promotion workflow
- Cloudflare Pages with Workers for fully edge-hosted Next.js
- AWS ECS / App Runner for teams requiring private VPC and custom infra
- next-sitemap or custom sitemap generation with change frequency tuning
- JSON-LD structured data: Organization, WebPage, Article, Product, FAQ
- Sentry integration with source maps and Next.js-specific instrumentation
Senior engineers, modern stacks, no hand-offs.
From greenfield products to long-running platforms — we build software that survives launch day and the year that follows.
Custom development
TypeScript, Node, Laravel, .NET — picked for the workload, not the resume.
- Clean-architecture by default
- Test coverage on critical paths
- Type-safe end to end
API & micro-services
REST, GraphQL and event-driven services with documented contracts.
- OpenAPI / GraphQL schemas
- Versioned + backwards-compatible
- Rate-limited + cached
Data layer
PostgreSQL, Mongo, Redis — modelled for the actual access patterns, not the ORM.
- Read replicas + sharding
- Migrations as code
- PII-aware schemas
Security baked in
OWASP-aligned reviews, secrets in vaults, dependency scans on every build.
- SAST + DAST
- Dependency CVE watch
- Audit-friendly logs
Predictable, audit-friendly delivery.
Every engagement follows the same stage cycle — so you always know what is happening, what comes next, and who owns it.
Discovery
Workshops, KPI alignment, technical baseline.

Replatform that scaled to 4× peak traffic.
A B2B SaaS replatform onto a modern TypeScript stack — shipped in 14 weeks with zero data loss and a 64% drop in P95 latency.
The tools we ship with.
Engineering that survives the first production weekend.
Most software fails not at launch but six months in — when traffic spikes, requirements drift and the original team rolls off. We design for that reality from sprint zero.
Architecture chosen for the workload
We pick a stack against the actual access patterns, expected load and team skill — never against trend cycles. The result is fewer rewrites, lower hosting bills, and a codebase your future engineers can navigate in an afternoon.
Tests where they pay off
Critical paths are covered with integration and contract tests; trivial getters are not. We aim for confidence at deploy time, not coverage-percentage theatre — and we wire CI to block regressions, not vanity metrics.
Observability from day one
Every service ships with structured logs, distributed traces and business-KPI dashboards. When something breaks at 2 a.m., your on-call has the timeline, the request and the user — not a haystack.
Documentation that engineers actually read
Architecture decision records, runbooks and onboarding paths live next to the code. New engineers contribute on day three, not week three — and audits stop being a fire drill.
How we make decisions.
Four non-negotiables that govern every engineering choice we make — from stack selection to incident response.
AI-assisted code review
Every pull request runs static analysis and ML-pattern checks before a human reviewer sees it — so engineers spend their review time on logic, not linting.
Observability first
Structured logs, distributed traces, RUM and alerting are wired in from sprint one. When something breaks at 2 a.m., the on-call has the full picture in seconds — not a blank Datadog screen.
Outcome-tied KPIs
Every sprint is reviewed against the business metric it was meant to move — conversion rate, latency, error budget — not story points or lines of code delivered.
Resilient architecture
Graceful degradation, idempotent retries, dead-letter queues and circuit breakers are default patterns, not afterthoughts. Systems that fail quietly are more dangerous than systems that fail loudly.
Three ways to work with us.
End-to-end delivery against a clear scope — discovery through launch with signed-off milestones at every sprint.
- Discovery + architecture estimate
- 2-week sprints, weekly demos
- QA, security review & launch
A senior pod of engineers and an architect embedded in your team — flexible roadmap, your repo, your rituals.
- 3–6 person senior pod
- Architect + tech lead included
- Integrates with your Jira & Slack
We run, patch, optimise and roadmap your platform — so your internal team can focus on new product work.
- 1-hour critical response SLA
- Monthly perf & cost review
- Quarterly roadmap planning
