Hey, I’m Simon 👋
I love creating - apps, videos, experiments - and sharing what I learn along the way.
You’ll find deep dives into React Native, app building, and the creative process behind it all.
I’ve been teaching developers for over 10 years and built Galaxies.dev 🪐 to help others make amazing apps - but this channel is where I explore, build, and just have fun creating.
