Next.js & React development

Next.js development covers the whole surface of a modern React application: how data is fetched and cached, which work happens on the server versus in the browser, how routes are structured, how the build is deployed, and how all of that holds up once real traffic arrives. Most of the difference between a fast application and a slow one is decided in those choices, not in the component code.

We build on the App Router with React Server Components, which means the browser downloads markup rather than a bundle that has to boot before anything appears. Data fetching happens on the server, close to the database or API, and only the components that genuinely need interactivity ship JavaScript. The practical effect is a fast first paint, a smaller bundle, and pages that search engines can read without executing anything.

Rendering strategy is chosen per route rather than globally. Marketing and content pages are statically generated and revalidated on a schedule; dashboards and account pages render per request; anything in between uses incremental regeneration. Getting this wrong is the single most common cause of both slow pages and stale data in React applications, and it is the first thing we look at on an existing codebase.

The work also includes the parts that are easy to defer and expensive to retrofit: type-safe boundaries between the client and server, an error and loading state for every route, structured data and metadata generated from the same source as the page content, and a deployment pipeline that runs typecheck, lint, and build on every commit.
