Callstack

✨ Cross-platform & full-stack app development We specialize in developing high-performing, cross-platform apps with React and React Native at their core — a combination we call React Universe that lets you enjoy better and faster apps, multiple platforms development, smoother running teams, and lower operational costs. ⚛️ Co-creators of React Native & Meta partners As official React Native partners, we work hand-in-hand with Meta, Microsoft, and Expo, just to name a few, to drive the evolution of this technology. Our team actively contributes to the React Native ecosystem by creating proposals, suggesting improvements, and maintaining key components, which means that your React Native product will always be at the forefront of innovation. 🙌 Building the Community We believe (code)sharing is caring, which is why we’re actively contributing to the Open Source Community by creating libraries, maintaining community repositories, and sponsoring contributors. Beyond code, we bring this spirit to life by hosting React Universe Conf and the React Universe On Air podcast.
