React Development Company
React is the right tool for applications that live behind a login, where the browser holds a lot of state and search engines are irrelevant. For public pages that need indexing, Next.js is usually the better answer, and we will say so.

Dashboards and internal tools
Dense interfaces with tables, filters and live data. React's strength: complex interactive state in the browser with no SEO requirement.
Authenticated application interfaces
The product behind the marketing site. Nothing indexable, so the extra machinery of a server-rendered framework buys nothing.
Design systems and component libraries
A documented set of components several teams build from, which is what stops a product accumulating eleven variants of the same button.
Migrations
Class components to hooks, Create React App to Vite, Redux to something lighter, or an older major version to current. Done incrementally, with the application shipping throughout.
State management, where React projects usually go wrong
The common failure is reaching for a global store on day one and putting everything in it. Two years later nobody can tell which part of the store a given screen depends on, and every change risks a re-render somewhere unrelated.
The distinction that keeps a React codebase manageable is between server state and client state. Server state — data fetched from your API — belongs in a data-fetching library such as TanStack Query, which handles caching, revalidation, loading and error conditions properly. Most of what teams put in Redux is server state badly reimplemented.
Client state — which modal is open, what is typed in this form, which tab is selected — mostly belongs in the component that owns it. A small amount is genuinely global, and for that Zustand or React's own context is usually sufficient. We reach for Redux when there is a specific reason, which is less often than its prevalence suggests.
Forms are the third category and deserve a dedicated library rather than hand-rolled state. React Hook Form with schema validation covers nearly every case and removes a surprising amount of code.
Performance work we actually do
React performance problems are predictable. These are the causes, in roughly the order we find them.
- Re-rendering a large tree because a new object or function identity is passed down every render. Fixed by stabilising the value, not by wrapping everything in memo.
- Long lists rendered in full. Virtualisation renders only the visible rows and is usually the single largest win on a data-heavy screen.
- Fetching in a child that the parent already fetched, producing waterfalls. Solved by fetching at the right level and caching properly.
- A bundle containing the whole application on first load. Route-level code splitting, and a hard look at the chart library that brought in a date library twice.
- Expensive work in a render rather than in a memo or outside the component.
- Images shipped at full resolution because nothing in the build pipeline is responsible for them.
