React development

Build dynamic, high-performanceweb applications with React JS

People spend their working day in your application, and its screens are slowing them down. That is where we use React. Our main plain React build is a multi-channel advertising platform: one interface for creating, scheduling and reporting on Facebook, Instagram and Google campaigns. We also use React through Next.js on most current web projects and through React Native on mobile.

The React work we do

Mostly interfaces that people use for hours, not brochure pages.

  • Workspaces for repeated daily tasks

    On the advertising platform, account managers define a campaign once and publish it to three networks, with approval steps and pause, resume and budget changes applied in one action. That is the kind of screen where React earns its place.

  • Live financial screens

    The crypto platform shows live rates with a configurable margin, customer portfolios and transaction history, built with Next.js and the MUI component library on a Laravel back end.

  • Reporting that compares sources

    The advertising platform shows each network's attribution side by side instead of merging them into one number, so the interface has to make differences readable rather than hide them.

  • Interfaces shared across web and mobile

    When a product also needs phone apps, React experience carries over to React Native. The UK garage-booking SaaS uses Next.js on the web and React Native on iOS and Android.

React, Next.js or React Native

The choice comes down to who needs to find the product and where it runs.

  • Plain React

    Suits an application behind a login, where search visibility does not matter and the server only supplies data through an API.

  • React through Next.js

    Suits anything public or mixed, because pages can render on the server. This is now our default for new web work. See our Next.js page for detail.

  • React Native

    Suits a product that needs real phone apps alongside the web. It shares the React way of working, though screens are still built separately for mobile.

How we approach a React build

Most of the risk in a complex interface sits in the data, not the components.

  1. Map the screens to the work

    We start with what users repeat all day and what they must not get wrong, then decide what deserves a dedicated interface.

  2. Fix the data shape

    Three ad networks with three campaign structures taught us to model the data first. Screens are far simpler once the API returns one consistent shape.

  3. Show working screens early

    Weekly demos on most projects let the people who will use the tool correct it early. Documentation for hand-over is kept up as the interface grows.

How a React engagement is set up

Scale it to the size of the product.

The advertising platform was a product build of about one year with six people, covering the back end and the three network integrations as well as the React interface. A smaller internal tool can be scoped and priced as a fixed project.

If your team only needs extra React capacity, hire developers from us who work to your process. Hourly rates begin from $20/h in USD, invoiced in USD, GBP, EUR or INR. We are an engineering team in India with 3–5 hours of overlap with the UK and Europe; US calls by appointment. We join your calls during the shared hours.

React projects we have delivered

Most of our work is delivered under NDA, so many projects cannot be named.

Questions about React work

Answers to what we are asked most often before a React project.

Which React version do you build on?
React 19. Version 19.0 was released on 5 December 2024 and 19.3.0 on 9 September 2026; this website runs on 19.3. On existing apps we work with the version you have and plan an upgrade separately if one is needed.
Can you take over an existing React codebase?
Yes. We read the code first and tell you what we would keep and what worries us. If the app uses React Server Components, one of the first checks is whether it has the security patches issued since December 2025.
Do you use a component library?
It depends on the product. The crypto platform uses MUI, which suits data-heavy admin screens, while this website uses Tailwind CSS with its own components. If you already have a design system, we build to it.
Do you also build the back end?
Usually. The advertising platform and the crypto platform both have Laravel back ends that we wrote. We can also work against an API your team owns.

Describe the interface you need

Tell us who uses it, what they do every day and what it connects to. We will suggest plain React or Next.js and explain the reason.
