Ready to solve your problems with React code?

Our team of expert React developers is ready to push your React project to the next level. Check the areas we specialise in below.

Web app development

Building scalable web applications

The Web started as a document-oriented network to quickly revolutionise to a place full of comprehensive applications, often outperforming their dekstop counterparts on both performance and feature levels.

New technologies are constantly emerging to bring additional features to the Web, such as Payments or Bluetooth connectivity. As a side-effect, the JavaScript development is getting more sophisticated, requring good understanding of existing Web capabilities and experience applying them to real world problems.

Our broad experience building React, React Native applications and a proactive attitude to cooperation with our clients is a guarantee for a stressless and smooth release of your web app and happy users.

Cross-platform development

Easily launch on new platforms

The React declarative approach to UI rendering and the ability to run JavaScript in almost any environment opens doors for sharing code on platforms that never had anything in common, such as mobile and web.

While you can technically share up to 100% of the code across all the platforms, the flexibility and adaptability of React and React Native make it easy to provide platform-specific features when necceessary.

Our experience developing cutting-edge applications on many platforms is a guarantee that our work is not only shared on targeted platforms as much as possible, but also that it preserves its platform-specific nuances to satisfy most demanding platform guideliness.

PWA development

Enhance your web experience for mobile users

You don't need to release a fully-fledged mobile app in order to improve overall user experience for the mobile web. You can do it right from the browser by releasing a mobile version of the website that works and interacts just like a mobile app.

React ecosystem is perfectly suited for PWAs with its rich ecosystem focused on mobile and accessibility. Thanks to React Native, the code that runs as a PWA can also be run as a part of a regular mobile app, giving you best of both worlds at the same time.

Electron development

Bring power of the web to desktop

By using Electron, we can move our web applications out of the browser sandbox, making it possible to do desktop interactions, such as working with the file system and documents that wouldn't be possible otherwise.

The use of web technologies makes it possible to reuse existing JavaScript code and develop the product much faster, especially compared to regular Windows or Mac OS development.

At Callstack, we are constantly looking for new ways to accelerate the multi-platform development and new ways of sharing the code between them. Electron is an important part of it.
