Mobile Apps

Mobile applications written on TypeScript, React Native version 0.61.5 and Expo (Bare workflow) version 37.0.10
For state management used Apollo Cache.
For data types used GraphQL Code Generator.
All components written on React Hooks.


We have written our own module for audio and video calls, which works on WebRTC, It also integrate in native applications code. A distributed signal server is also written from scratch. It allows you to create large audio and video conferences.


Web is developed on TypeScript and React.
For routing used react-router. Some components are reused using react-native-web. For styles using linaria. Also, all lists are virtualized and optimized for performance.

Desktop Apps

Desktop applications work on Electron.
All applications are created with one command. Also, optimization was performed for each of the available platforms.


Used technologies: NodeJS, TypeScript, GraphQL, Redis, MongoDB. All resolvers typed. All database queries are optimized and built on aggregation, which allows you to work under high loads. Socket server designed as a separate microservice, this allows to replicate it. For distributed work of connected users in real time, Redis is used. This ensures the smooth operation of audio and video calls in large conferences.

Do you need a Starter Kit?

Our goal is to allow people to integrate chat features into their existing products, as this saves time.

In addition, this product can be the basis for any type of application, because the architecture makes it easy to scale and modify it for any needs. You do not need to get involved with code performance. Many components are optimized for performance. The server part is easily scalable even on weak hardware, which saves resources. Many components and logic can be reused. Based on this product, there is everything to quickly start making any functionality.

This is a quick start for any team. Those who need to move fast understand the value. And those who worked in large distributed teams understand the value of a well-built architecture.

For a better understanding of architecture, you can read documentation.
