Watching Simons videos always taught me how to solve real world problems but having a live meeting with him revealed so much more about why he invest so much into his courses and videos. He simply wants to see us succeed and find fulfillment in learning and becoming better developers.

Absolutely the best courses available! Simon covers everything you need to get started with React Native. If you enjoy his helpful free content, I highly recommend checking out the professional courses. They provided me with valuable insights and motivation to begin rewriting my existing Swift app. Thank you, Simon!

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 worked through a couple of authentication tutorials and they have been very helpful. Simon also jumped on a call with me which was great to touch base.

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.
