Hi! I’m John, I write all of the Unity tutorials on Game Dev Beginner. I've been working as a professional game composer for the last 10 years and I've been writing about game development in Unity for the last 6. I started by writing audio-related tutorials on my own site, before expanding to general game development guides for beginners when I started Game Dev Beginner in 2020.
