Hi. I'm John Carmack.
I'm a software engineer focused on production LLM/AI and geospatial/GPU systems. Rust and TypeScript, deck.gl and luma.gl, and the cloud infrastructure that runs them. Lately: primary author of a safety-critical aviation desktop application, lone architect of a real-time analytics platform.
Not the Doom guy. Different guy.
