Aaron Castelyn

By day I'm an enterprise software engineer — the kind of work that involves large systems, real constraints, and making things that have to hold up at scale.

On the side I run Mindplay with Aaron — a YouTube channel where I explore AI and game development in Unreal Engine 5. Reinforcement learning, local LLMs, behaviour systems — the kind of things that make games feel like they're thinking rather than following a script.

The workshops are the hands-on extension of that — small, focused, live sessions where you build something real and walk away with a working pipeline.
