Mark Barney — Personal Website
Mark Barney is a software builder and consultant based in Connecticut, USA.
He spent about 15 years in the games industry scaling MMOs to eight-figure
revenue, and now ships web and mobile apps in weeks by directing LLMs
(Claude, GPT, and others) as his development team — acting as the product
manager and architect while the models write and iterate on the code.
Recent work includes the iOS games Peekaboo Plunk and Peekaboo Calm, an
ARC-AGI research platform at
arc.markbarney.net, and
experiments in human-versus-LLM reasoning. He is open to consulting.
