Next.js Development

Performance as discipline

Next.js 16React Server ComponentsCore Web Vitals
The problem

A large share of users abandon a site that takes more than 3 seconds to load. A slow site loses customers before it even shows itself.

How we work

App Router, React Server Components, Turbopack — a pinned Next.js 16 stack, not whatever the latest unstable release happens to be. The goal is green Core Web Vitals, measured with Lighthouse on every deploy, not promised in words.

The process
01

Rendering strategy

Server components by default, client components only where interactivity is needed: less JavaScript shipped to the browser.

02

App Router

Shared routing and layouts, streaming and Suspense where content is slow, not everywhere out of habit.

03

Pinned stack

Turbopack in dev, an optimised production build — a stable version, not whatever the latest release happened to be on deploy day.

04

Real measurement

Lighthouse and Core Web Vitals checked on every deploy, not just at launch.

What's included
  • App Router with React Server Components
  • Optimised rendering: less client-side JS where it isn't needed
  • Optimised images and fonts (next/image, next/font)
  • Core Web Vitals measured on every deploy
Who it's for

For those who already understand that a slow site loses customers before it can convince them.

Who it's not for

Not for those chasing the most talked-about framework of the moment — we choose the stack for the project, not the hype.
