Summary
👤
SeniorCristian Díaz is a founder and hands-on spatial computing engineer with 11 years of experience shipping first-of-their-kind products that make new platforms genuinely useful and accessible. He co-founded Realitycheck to build inclusive spatial experiences, open-source tooling, and research—projects include The Green Spurt for Apple Vision Pro, the Preflight OpenUSD inspector, and a Reality Composer Pro reimplementation documented in a seven-part Deconstructed series. His career thread is building where no playbook exists: interactive media in Chile, Bluetooth health devices, an AI automotive assistant, and visionOS accessibility patterns before the hardware shipped. He combines product-grade engineering (TCA, RealityKit, OpenUSD) with accessibility-first design so features work for VoiceOver, Switch Control, and diverse interaction styles. A frequent speaker and community organizer in the visionOS ecosystem, he also publishes technical deep dives and maintains several practical open-source libraries that bridge RealityKit/ARKit/Metal and USD workflows. Based in Berlin, he’s as comfortable profiling tight macOS render loops as mapping cross-disciplinary requirements between hardware, firmware, and ML.
