Component architecture
Small components with clear props, custom hooks for shared logic and state kept close to where it is used, so new screens reuse rather than copy.

React expertise
React expertise our developers bring.
We screen React developers on the decisions that matter as an app grows: how components are split, where state lives and what re-renders when.
State that stays predictable
Server data in TanStack Query, shared client state in Redux Toolkit or Zustand, form state in React Hook Form — and no more prop drilling.
React 19 where it helps
Actions, useOptimistic and use() for forms and data loading, and the React Compiler in place of hand-written memoisation.
Performance and bundle size
Profiling wasted re-renders, virtualising long lists, splitting code by route and removing dependencies that bloat the bundle.
Accessible by default
Semantic HTML, keyboard support and focus management in modals and menus, checked against WCAG 2.2 AA in every pull request.
Tests that survive refactors
React Testing Library tests written around user behaviour, Playwright for critical journeys and Storybook to review components in isolation.
What they build
What React developers can build for you.
Most React requests from UK teams fall into one of these — from a first design system to a codebase that has become hard to change.
Data-heavy product screens
Tables with server-side filtering and sorting, bulk actions, charts and role-based views that stay responsive as the data grows.
Design system components
A shared component library built on accessible primitives, themed from your design tokens and documented in Storybook.
Long forms and applications
Multi-step quotes, applications and onboarding flows with saved progress, conditional questions and error messages people understand.
Live operational screens
Dispatch boards, order queues and chat updated over WebSockets, with optimistic updates that reconcile cleanly with the server.
Front ends for your API
React clients for Node.js, Django or FastAPI services, with typed API calls, proper session handling, and loading and error states designed in.
Legacy React modernisation
Class components, Enzyme tests and Create React App builds moved to hooks, React Testing Library and Vite, one module at a time.

Developer seniority
The right level for the work.
Every engagement is staffed with senior engineers. What changes is how much architecture and leadership the work needs around them.
Senior React developer
Takes features from ticket to reviewed, tested, deployed code without hand-holding. The right choice for most roadmap work.
Lead engineer or architect
Sets the React architecture, reviews the team's code and plans migrations, upgrades and scaling work.
A small blended pod
A React developer with backend, QA or design support, coordinated by one delivery owner for larger scopes.
Engagement models
Ways to hire React developers.
Pay by the hour for bursts of work, reserve a dedicated developer for your roadmap, or hand us the whole project.
Hourly React developer
From £20 per hour
Backlog work, fixes, integrations, and flexible sprint support
- Weekly billing, daily written updates, code review, and no long-term lock-in.
Dedicated React developer
From £2,900 per month
Ongoing delivery, product teams, and roadmap acceleration

Prices are in GBP. Every estimate is confirmed in writing after a discovery call — the figures above are where engagements start, not a quote.
How hiring works
From brief to first commit.
The goal is not just to introduce a React developer — it is to make the first week useful and the work visible from then on.

Why Techsleight
Why hire through Techsleight.
What you can hold us to — and what happens if something is not working.
You choose who joins
You see profiles and talk to the React developer before anything starts, and nobody joins your team without your say-so.
Senior, production engineers
People who have shipped and supported real products — reviewed for code quality, testing habits and communication, not just a CV.
They work your way
Your repositories, tickets, stand-ups and review rules. Daily written updates and a weekly demo keep the work visible.
No lock-in
Hourly, dedicated or project-based, with short notice periods. Scale up for a launch and back down after it.
You own the code
Code, IP and documentation belong to you from day one. NDA before any detailed conversation, if you need one.
UK-focused delivery
UK business hours, GBP pricing and a contract with a UK company. Our engineers are based in the UK and India.
A whole team behind one hire
Backend, QA, DevOps and design colleagues are there when the React work needs them — without you hiring for each role.

Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
Can you upgrade an old React codebase to React 19?
Yes. We start with an audit of versions, class components, legacy APIs and test coverage. React 19 removed ReactDOM.render, string refs and legacy context, so we first move to React 18.3, which warns wherever those APIs are still used. We fix the warnings, add tests around risky screens, then upgrade React and its libraries while feature work carries on.
Do we still need Redux?
Often not for new work. Much of what ends up in a Redux store is really server data, which TanStack Query caches and refreshes for you; what is left usually fits in Zustand or context. Redux Toolkit still suits large apps with complex client-side workflows — and if you already run Redux, we modernise it rather than rip it out.
Can you build React interfaces to WCAG 2.2 AA?
Yes. Accessibility is part of our definition of done: semantic HTML first, ARIA only where it is needed, keyboard and screen-reader checks on new components, and automated axe checks in CI. We can also audit an existing app and fix issues in order of impact. Sign-off on your Equality Act duties stays with you — we do not give legal advice.
Can the same developers work on our React Native app?
Often, yes. Components, hooks and state management carry over, and shared TypeScript code can serve both apps. Mobile adds its own work — native modules, device testing and App Store and Google Play releases — so for app-heavy roadmaps we pair your React developer with a React Native specialist.
How much does it cost to hire a React developer in the United Kingdom?
React developer rates at Techsleight Labs start from £20/hour for flexible work and from £2,900/month for dedicated monthly capacity. Fixed-price React projects are quoted after discovery, once scope, integrations, risks, and timeline are clear.
How quickly can a React developer start?
Most React engagements start within 5–7 working days of sign-off, and urgent work can sometimes start within 48–72 hours. For larger projects, we first confirm scope, architecture, milestones, and the right senior engineer fit before kickoff. We support UK teams with written updates, planned demos, and timezone-aware handover.
Can I hire one React developer or a full team?
Yes. You can hire a single React developer, add a small pod with QA and DevOps, or ask us to manage the complete project. We match the model to your current team, delivery pressure, and budget.
Are your React developers senior?
Yes. Our hiring pages are built around senior production engineers, not junior bench resources. Every developer is reviewed for commercial project experience, communication quality, code quality, testing habits, and ability to work inside existing teams.
Do you work with existing React codebases?
Yes. We often join existing React projects to fix performance, unblock releases, add features, improve test coverage, or modernise architecture. We start with a codebase review so the first sprint is practical rather than theoretical.
What happens if the React developer is not the right fit?
Tell us early. We will look at the cause with you — the brief, the onboarding or the match — and agree the next step together, such as more technical oversight, a different engagement model, or ending the engagement on the notice terms in your contract. The goal is a useful working relationship, not lock-in.
