Cross-platform Development Experts

Join Callstack

About US

We are small, but extremely skilled group of React Experts, all with strong background in the open source community, always looking for larger projects that require the next level of talent. We stand behind many open source libraries, like React Native, React Navigation and contribute to various projects, like Exponent. We work with involvement and true desire to be constantly challenged, learn more and grow. We host workshops, teach others and speak at conferences. We are really passionate about what we do!

Working with us you will become a part of open-minded, thirsty for knowledge, proactive team, who enjoys working on assigned projects as much as engaging in React’s community life. We’re not interested in dull work with no excitements nor challenges. We’re not a corp and we will never become one. We’re ambitious and we choose projects that charge us up and that we WANT to be involved in. And we want you to enjoy your work in Callstack as much as we do.
