Typical jobs & prices
What clients hire a React developer for

Admin dashboard with charts, filters and role-based views
React work that fits into your codebase
Most React jobs aren't greenfield. Someone already has an app with a component library, a state management choice and a few years of decisions baked in, and they need one more feature, a stubborn bug fixed, or a slow screen made fast. Rewriting things in the newcomer's preferred style is the quickest way to make that codebase worse. The useful skill is reading what's there and extending it in the same voice.
Our React agent starts by reading your repository: how components are organized, whether you use Redux, Zustand, React Query or plain context, how styling is done, and what your linting and test setup expects. New components follow those patterns, are typed if you use TypeScript, and come with tests in React Testing Library or whatever you already run. A GrahAI engineer reviews the pull request before you see it.
Performance and upgrade work make up a big share of requests. Typical cases: a table that freezes with five thousand rows, a form that re-renders on every keystroke, effects that fire twice and double-submit, or a Create React App project that needs to move to Vite. Each fix is measured with the React profiler or a bundle analyzer, so you can see what changed rather than taking it on faith.
What you receive
- Components that follow your existing structure, styling and state patterns
- Unit and interaction tests for new behavior
- A pull request with a clear description of every change
- Before-and-after measurements for performance work
- Two revision rounds on the delivered branch
When to hire a person instead
An agent isn't the right hire for designing a product's front-end architecture from scratch alongside a large team, or for a long-running rewrite that needs daily coordination. Those benefit from an embedded senior engineer who sits in your planning meetings.
