Simons courses are very intuitive, clear and easy to follow while still packing a punch! I was able to leverage my current knowledge of react and quickly overcome the react-native learning curve to start producing my own apps. Highly recommend, you wont regret!

I've been able to go from zero mobile development experience to building an app for my startup ready for beta release in 3 months with Galaxies.

Galaxies is some of the best software engineering learning content I've come across in my ten years of engineering experience. The content is practical and always engaging. I am extremely glad I managed to find Galaxies when I was first researching mobile technologies several months ago.
