React interfacesthat performand convert.

We build component-driven React frontends with TypeScript, React Query, and state management that does not leak between screens. Production interfaces, not demo screens.

Is React right for your project?

React fits some products and is overkill for others. Here is when we recommend it, and when we point you at something else.

SINGLE PAGE APPLICATIONS

Dashboards, CRMs, and product apps where users live in one screen for hours. Client-side routing, instant view changes, and a state model that keeps up.

COMPLEX SAAS DASHBOARDS

Tables that filter, charts that update, and forms with deep state. Redux Toolkit, Zustand, or React Query depending on what the data actually looks like.

CROSS-PLATFORM PRODUCT TEAMS

Shared business logic and types ready to lift into React Native if a mobile app is on the roadmap. We design for the share boundary from day one.

What reverseBits React projects deliver

We engineer frontend codebases teams can maintain a year later, not throwaway prototypes.

Component architecture that scales

An atomic design system with shared primitives, composed patterns, and feature components. Junior engineers ship a feature without rewriting the button.

AtomicDesign system

State management that fits the data

Redux Toolkit for global client state, Zustand for local state, React Query for server state. We pick the right tool for the data shape, not one tool for everything.

Zustand& Redux Toolkit

TypeScript across the codebase

Strict mode, typed props, typed API contracts, typed Redux slices. The bugs that make it to staging are the ones tests catch, not the ones the type system misses.

100%Type safety

React Query for server state

Background refetching, cache invalidation, optimistic updates, and retry logic. Your UI stays in sync with the API without a glue layer of useEffect calls.

CacheInvalidation

Performance budgets that hold

Code splitting, lazy routes, suspense boundaries, and React Profiler audits. Lighthouse scores above 90 on the pages your users actually visit.

90+Lighthouse score

Tests that run in CI

Jest and React Testing Library on every PR, Playwright for the critical flows. Tests that fail when the UI breaks, not when an implementation detail changes.

100%Test coverage

React problems we fix

Common React problems and how we solve them.

The Problem

Prop drilling and unmaintainable code

Props passed through ten components to reach the one that needs them. Every refactor breaks three screens.

Re-render storms

A single state change re-renders half the page. The interface stutters on mid-range laptops.

Global state used as a junk drawer

API responses, form values, and UI flags all in Redux. Every dispatch ships a 200-line reducer change.

Our Solution

Co-located state with Zustand or context

State lives where it is read. No global stores for things that belong to one screen.

Memoization where it actually matters

React Profiler points at the slow renders. useMemo and useCallback go on the components that re-render too often, not everywhere.

Server state separated from client state

React Query handles caching, refetching, and invalidation for API data. Redux or Zustand handles the small amount of state the UI actually owns.

Why reverseBits for React

We ship frontends that survive a year of feature work without rewrite tickets. Every component is typed, every render is intentional, and every PR ships with tests that run in CI.

Clutch rating across reviews

Frontend engineers, not full-stack generalists

Engineers whose day job is React, hooks, and the rendering model. Not a backend engineer borrowing a sprint.

Pixel-accurate Figma builds

We work from design tokens, not screenshots. Spacing, typography, and components match the design system on every screen.

TypeScript by default

Strict mode, typed API contracts, typed forms. Compile-time safety catches the bug class that ships to production.

Accessibility built in

Semantic HTML, ARIA where it belongs, keyboard navigation, WCAG checks in CI. Screen readers work because the markup is right.

Stop shipping React frontends that fall over after the first feature push. Get a codebase your team can maintain a year later.

React FAQ

Common questions about React projects.

Ready to build your React product?

Yes. React is a frontend library and does not care what serves the API. We have shipped React on top of Django, FastAPI, NestJS, and Express backends. We use React Query or RTK Query to handle the API contract, and TypeScript types match the backend schema so a contract change shows up at compile time, not in production.

Both, depending on the data shape. Redux Toolkit makes sense for global client state with complex relationships. Zustand is lighter when one or two screens own most of the state. React Query handles server state in either case. We do not put API responses in Redux. That is the most common mistake we untangle on inherited codebases.

Most marketing pages should not be a React SPA in the first place. For products that need both, we move SEO-critical routes to Next.js with server-side rendering or static generation. For pure SPAs, we use prerendering for crawlable routes and structured data for everything else. Plain client-rendered React is fine for an authenticated product, not for a public marketing site.

Not in one shot. We replace screen by screen, starting with the highest-traffic page. The React app lives next to the legacy code with shared routing or a wrapper. Six months in, you have measurable wins on the migrated screens and the legacy code keeps shipping. Big-bang rewrites kill product velocity for a year.

Some of it. Business logic, types, validation, and API clients can live in a shared package. The UI layer does not transfer because React Native renders to native components, not the DOM. We design the architecture so the shared layer is real and the platform-specific layer is small. If a mobile app is on the roadmap, we build for that share boundary from day one.
