Hello, I'm Neil Koo.

I specialize in gameplay systems, AI, and debugging, with over 10 years building and shipping games across PC, console, and mobile. I’m happiest deep in a hard problem — untangling an elusive bug, stabilizing a complex system, or building the tools that help a team move faster.

I’m currently with Gunmetal Games on Rewind 99 as a Senior Gameplay Programmer on contract. Before that, at Invoke Studios, I contributed to Dungeons & Dragons: Dark Alliance and helped take WARLOCK: Dungeons & Dragons from prototype through vertical slice.
