React Development
Fast, maintainable React web applications
We build fast, maintainable web applications in React for UK businesses, with secure, well-architected front ends that connect cleanly to your back-end systems.
What React development with Talk Think Do means
React development is the building of web applications with React, the most widely adopted front-end library. It is the right choice when you need a responsive, interactive web experience that is fast to use and maintainable for years. This page is for teams looking for a React web partner in the UK.
We focus on the web: single-page apps, portals, and dashboards, with front ends that connect cleanly to your APIs and back-end systems. If you need a mobile app, see our React Native development service.
The front-end problems we are brought in to solve
Most React projects start with one of these. We build to make sure they do not come back.
A slow, clunky interface
Pages load slowly, interactions feel sluggish, and the UI looks dated. Users notice, bounce rates climb, and the product feels harder to use than it should be.
A front end out of step with the back end
The UI and the systems behind it were built in isolation. Integrations are brittle, logic is duplicated, and a change on one side keeps breaking the other.
Inconsistent, unmaintainable UI
With no design system, every screen reinvents the wheel. The codebase has grown tangled, small changes take days, and onboarding a new developer is slow and risky.
Inaccessible or invisible to search
The app fails accessibility checks and key content is hidden behind JavaScript, so search engines and AI crawlers never see it. You lose users and visibility at the same time.
React development capabilities
Web applications, component libraries, and front ends that connect cleanly to your systems, all built to last.

AI-augmented React engineering
Every engineer uses AI-augmented development as part of our standard process. That makes delivery 40 to 50% faster than a traditional team, with 84% of our code now AI-authored and human-reviewed. The figures are measured on live projects and published openly.
Architecture, accessibility, and quality decisions stay with experienced engineers. Read how we measure it in our AI Velocity Report.
How a React front end connects
A layered architecture from the React browser app through the API layer to your back-end services and data on Azure.
Our React delivery process
A structured, transparent process that keeps the front end and back end moving together.
Discovery and UX scoping
We map user journeys, the data the front end needs, and how it connects to your systems. You get a clear scope, a component plan, and effort and value estimates before any build begins.
Architecture and design system
We define the React architecture, state management, and a component library aligned to your brand. API contracts are agreed up front so the front end and back end stay in step throughout.
Build in React
We deliver in agile sprints with AI-augmented engineering, TypeScript, and automated testing. Regular demos mean you interact with working software, not mockups, at every stage.
Accessibility, performance, and security
Every build is checked against accessibility standards and performance budgets, put through our security review, then scanned for open-source licence issues before it ships.
Launch and support
We deploy to Azure with zero-downtime releases and 30 days of free post-launch care. Optional managed support keeps your React application healthy, secure, and current.
React front ends behind a luxury gym platform
For Third Space, London's luxury health club collection, we built Atlas: a complete rebuild of their digital ecosystem with React-based web front ends on a cloud-native Azure platform. It spans member-facing web, instructor tools, and an operations portal, runs at 99.99% uptime, and serves more than 40,000 monthly active members.

"We'd outgrown our off-the-shelf solution. Stability was a real issue: members couldn't always book classes, which was a crisis for us. Talk Think Do built something that scales with our ambitions, stable, flexible, and ready for the future."
Colin Waggett
CEO, Third Space
A React web specialism inside a full-stack consultancy. We build the front end and the systems behind it, so your interface and your data stay in step, with full source code ownership on every engagement.
About Talk Think Do
Talk Think Do is a UK-based software development company founded by Matt Hammond and headquartered in Bournemouth, Dorset. We are a Microsoft Solutions Partner with designations in Azure Infrastructure, Digital and App Innovation, and DevOps and GitHub.
We build React and React Native front ends on Azure, backed by .NET services, so the interface and the systems behind it are designed together. We hold ISO 27001 certification, Cyber Essentials Plus accreditation, and approved Crown Commercial Service supplier status on the G-Cloud and Digital Outcomes frameworks.
Our clients include:
- Third Space
- Department for Education
- CalMac Ferries
- Hachette Learning
- Explore Learning
AI-augmented development is central to how we work. Every engineer uses AI tools such as Cursor, Claude Code, and GitHub Copilot daily, and we run a quarterly evaluation cycle to keep improving. The result is React software delivered faster, without compromising architecture, accessibility, or code quality.

What is React development?
React development is the building of web user interfaces with React, a widely used JavaScript library. It is well suited to interactive single-page applications, dashboards, and customer portals. Talk Think Do builds React web applications for UK businesses and connects them cleanly to back-end systems on Azure.
Do you build web apps or mobile apps with React?
This service is for React web applications that run in the browser. For cross-platform iOS and Android apps we use React Native, a related but distinct framework. See our React Native development service for mobile.
Can you connect a React front end to our existing back end?
Yes. That is a core part of what we do. We connect React front ends to .NET services and other back ends through clean APIs, including the backend-for-frontend (BFF) pattern, REST, and GraphQL, secured with OAuth 2.0 and JWT. See our API and integration services.
Do you use TypeScript with React?
Yes. We build in TypeScript by default. Static typing reduces a whole class of runtime errors, makes refactoring safer, and gives AI-augmented tooling clearer signals to work with. It is part of how we keep React codebases maintainable over time.
Will my React app be accessible and fast?
Yes. We build to WCAG accessibility standards and set performance budgets so your application is usable and fast on real devices. We also make sure content is reachable for search engines and AI crawlers, not hidden behind JavaScript-only interactions.
Can you take over or fix an existing React app?
Yes. We regularly take on existing React codebases, including apps built quickly with AI tools that now need to scale. We assess the code, stabilise it, and bring it up to a maintainable, well-tested standard. Our prototype to production service covers this in detail.
How much does React development cost?
A focused React application typically starts around £50,000, with larger platforms running higher depending on scope, integrations, and design complexity. AI-augmented delivery means more is built within the same budget. We provide a detailed estimate after a free discovery session.
