clients and their users. We have extensive experience in building modern multimedia solutions and offer consulting & development services in, among others, the following areas: audio/video real-time streaming and processing, mass storage, performance, and scalability. In most of our projects, we use React, React Native, Node.js, Python, Ruby on Rails, and Elixir — but we do not like to limit ourselves. We also contribute to the open-source community. We are the co-creators of React Native and we are the ones behind such libraries as React Native Reanimated or React Native Gesture Handler
