Senior🎓
Top SchoolMark Johns is a creative technologist and founder with 15+ years of experience shipping inventive games, tools, and AR prototypes that blend engineering, design, and emergent AI. As owner of Doomlaser he has released indie hits and cult experiments—from the long-running macOS utility Cursorcerer to genre-bending titles like Space Barnacle and Shit Game—and architected Dream Factory, an early Unity LLM-driven theater engine for real-time AI storytelling. His background includes leading engine rewrites and creative direction on Tap Tap Revenge (tens of millions of players) and prototyping shared-space AR interactions at Niantic, giving him rare cross-platform expertise from OpenGL and mobile to ARKit/ARCore. Based in Champaign, IL, he thrives at the intersection of product, rapid prototyping, and expressive tech, frequently turning niche technical feats (undocumented Carbon APIs, procedural systems, LLM-driven runtime control) into polished, playable experiences.
