Positioned as the first mission in the Galaxies.dev learning path, this course is built to take you from beginner to someone who has actually published a mobile app, using React Native and the current architecture that recently became its standard.

What's included

  • Video lessons paired with practical, hands-on projects
  • Code reviews as part of the learning process
  • Guidance built around the Expo framework, which Meta recommends for a smooth start

Why it's worth doing now

React Native is expected to see a major update to version 1.0, and getting comfortable with the framework now positions you ahead of that shift as more companies adopt it. By the end, you'll have published your first iOS and Android app and gained practical experience most job candidates don't have.

Why this course?

  • A unified path to your published application. This is the first mission in the Galaxies.dev ecosystem, providing a full-fledged bootcamp-style learning experience at a more affordable price.
  • Learning React Native. We teach the latest React Native architecture, which recently became the standard. You'll gain current skills to develop with modern development speeds.
  • Your first iOS and Android application. The Expo framework, recommended by Meta, ensures a smooth start. The course includes proven materials created in collaboration with language developers.
  • An advantage in the job market. React Native is expected to undergo a significant update to version 1.0. Learn mobile development now to be prepared as more companies start actively using this tool.

What you will get:

  • In-depth knowledge of React Native and Expo.
  • Practical experience in creating and publishing applications.
  • Modern skills that will help you stand out among candidates.

This course is the perfect starting point for your journey in mobile development. Ready to embark on the mission?
