Featured success stories


React JS at its finest

As a seasoned React development company, we know how to make the most of React’s potential and create performant, easy-to-maintain applications both for mobile and desktop.

Fast rendering

While we can’t reverse people’s continuously shrinking attention span, we can use React’s virtual DOM to adapt and re-render any changes as quickly as possible. This results in increased performance, smooth user navigation, and, ultimately, in an improved user experience.

Reusable components

Creating components that can be reused across different parts of the codebase is a core feature in React. We leverage this functionality to make sure that your code is as DRY and efficient as possible.

Widespread use among world-class companies

From Alipay to WhatsApp, React is used by some of the leading companies out there. We use the same engineering standards and libraries as they do, so you can be sure that your product will have the highest level of performance and reliability.

Compatibility with different engineering environments

React is an open-source library, meaning it can be integrated with any other engineering environment such as Node JS or Redux. By opting for React and *instinctools, you can ensure that your project runs smoothly regardless of the environment.
