Next.js & React Development

Fast, accessible and search-friendly web applications built with Next.js and React, from content-driven websites and customer portals to data-dense SaaS dashboards.

All solutions
THE OPPORTUNITY

Built around your operation.

We build web applications with React and Next.js: product dashboards, customer portals, content-driven websites and SaaS front ends. We choose the rendering approach for each route, whether static, server-rendered or client-side, and build typed, component-based interfaces that a team can keep extending.

Why it matters

The front end is where users judge your product. Slow loading, layout shifts and inaccessible controls cost conversions, and pages that depend entirely on client-side JavaScript are harder for search engines to process and may be unreadable to AI crawlers that do not execute JavaScript. Getting rendering, data fetching and performance right early avoids an expensive rewrite later.

Core scope

  • Next.js applications with server rendering and static generation
  • React interfaces, design systems and dashboards
  • Core Web Vitals, accessibility and technical SEO
HOW WE DELIVER

A deliberate approach.

  1. 01

    Define routes, rendering strategy, data sources and performance budgets

  2. 02

    Build a typed component library and design tokens shared across the product

  3. 03

    Implement pages, forms, state and API integration with automated tests and preview deployments

  4. 04

    Measure Core Web Vitals, accessibility and SEO before launch and monitor them afterwards

WHERE IT FITS

Typical use cases.

Common situations where teams bring us in for this work.

  1. 01

    SaaS dashboards and admin panels

    Data-dense interfaces with tables, filters, charts, role-based views and live updates that stay responsive as data grows.

  2. 02

    Customer and partner portals

    Authenticated portals for orders, documents, support requests or account management, connected to your existing backend and CRM.

  3. 03

    Marketing and content websites

    Prerendered or server-rendered websites with structured metadata, clean URLs and content that remains readable without JavaScript.

  4. 04

    Front-end modernisation

    Moving a legacy front end or an older React codebase to a maintainable Next.js or modern React architecture, route by route.

COMMON QUESTIONS

Questions buyers ask.

Straight answers about scope, risk and ownership before you start a project.

01

Should we use Next.js or plain React?

React is a library for building interfaces; Next.js is a framework built on React that adds routing, server rendering, static generation and server-side endpoints. Next.js is usually the better default for public, search-visible pages and full-stack products. A client-rendered React app, often built with Vite, can suit internal tools behind a login where search visibility does not matter.

02

Is a React website bad for SEO?

Not if it is rendered appropriately. Google can render JavaScript, but some crawlers, including major AI crawlers, do not execute it at all. Server rendering or prerendering important pages, using real links and giving each page its own title, description and canonical URL makes the content reliably crawlable.

03

How do you improve Core Web Vitals?

We measure first, using field data where it exists and lab tests otherwise, then fix the specific causes: large or late-loading hero images, render-blocking CSS and JavaScript, web-font loading, layout shifts from unsized media and long tasks that delay interaction. Every change is verified against the same measurements.

04

Can you work with our existing codebase?

Yes. We start by reviewing the architecture, dependencies, tests and build pipeline, then agree whether to improve incrementally or migrate specific routes. Most modernisation can happen without stopping feature work.
