React development

React interfaces that feel instant

React front ends for web apps, dashboards, portals and interactive product experiences, built as clean, typed components your team can keep building on.

Plan my React buildIs it right for me?

What you walk away with

  • React front end in TypeScript
  • Reusable component library
  • Connected to your APIs
  • Tested on every screen size
  • Handover docs for your team

Is React the right fit?

We build on several platforms, so we'll tell you straight when another one suits you better.

(a great fit when)

  • You're building a web app, dashboard or customer portal
  • Your product needs rich interaction, not just pages
  • You have (or need) an API and want a front end for it
  • You want a component library that matches your design system

(we'd point you elsewhere if)

What we build on React

Pick one piece or the full build, planned together with your brand.

  • 01

    Web apps & portals

    Logged-in tools, dashboards and customer portals built around real workflows.

  • 02

    SaaS front ends

    Onboarding, settings, billing and the everyday screens your users live in.

  • 03

    Figma to React

    Your design system rebuilt as typed, documented, reusable components.

  • 04

    API integration

    Front ends wired to your back end, CRM, payments or third-party services.

  • 05

    Interactive experiences

    Configurators, calculators, animations and data visualisation.

  • 06

    Code reviews & rescue

    Audits and refactors for React codebases that have become hard to change.

How a build runs

Four stages, with your sign-off at the end of each.

  1. Step 01

    Scope

    Screens, user flows and the data each one needs, agreed before any code.

  2. Step 02

    Design

    Components and screens in Figma, organised as a system, not one-offs.

  3. Step 03

    Build

    TypeScript components and screens, shipped in short, reviewable releases.

  4. Step 04

    Hand over

    Documentation, tests and a walkthrough so your team can carry on.

After launch, we stay

React apps work best when someone keeps them current. We maintain the code, its dependencies and the hosting behind your front end.

  • Dependency updates

    React, libraries and security advisories handled in small, tested updates.

  • Bug fixes & small features

    Issues fixed and improvements shipped from your monthly support hours.

  • Hosting & deployments

    Build pipelines and environments on Vercel, Netlify, AWS or your own server.

  • Error monitoring

    Error tracking set up, so problems are spotted before users report them.

  • Browser & device checks

    Screens retested as new browser and OS versions arrive.

  • Performance

    Bundle size and load times watched, so the app stays quick as it grows.

Annual maintenance contract

One agreement, the whole year covered

  • One fixed yearly fee, agreed upfront
  • Support hours every month for fixes and changes
  • Agreed response times, with urgent issues first
  • A monthly report of what was done and what's next
  • The same team that knows your build

Common questions

Can you join our existing React project?+

Yes. We regularly pick up existing codebases, review them first and then add features or tidy up what's slowing your team down.

Do you use TypeScript?+

By default. It catches mistakes early and makes the code easier for the next developer to understand.

React or Next.js?+

If search engines need to find your pages, or speed on first load matters, Next.js (which is built on React) is usually the better choice. For logged-in apps, plain React works well.

Can we hire a dedicated React developer from India?+

Yes. You can work with us on a project or a monthly retainer, with overlapping hours for calls in US, UK, European and Australian time zones.

Do you maintain React apps after launch?+

Yes. On a monthly plan or an annual maintenance contract (AMC), we keep dependencies current, fix bugs, manage hosting and deployments and monitor errors. We also maintain React apps built by other teams.
