XR + AI Researcher | XR Systems & Validation Engineer

Building the intelligence layer — and making XR systems reliable in the real world.

Focused on debugging, validating, and scaling XR systems across devices, environments, and users.

XR resets every session. Apps stay siloed. Intelligence never compounds.

OpenSpatialAI is the infrastructure layer for spatial systems that maintain memory, context, and reliable behavior across sessions and environments
