NASCAR 3D TABLETOP — INTERNAL R&D
If you have a headset, this is the part of my work you can actually stand inside. Xtadium is Meta's featured immersive sports app — live NBA, UFC, NASCAR and EuroLeague in 8K 180°/360°, multi-camera, watch parties. I work on it full-time, and I own its spatial UI, notifications, onboarding, localization and the spin-off architecture the other two apps ship on.

2023–2024 · LURTIS AI · UNITY EDITOR TOOL
A Unity tool for creating and co-designing 3D scenarios, from single rooms to whole worlds, meant to buy design time back for narrative and gameplay. Publicly funded R&D. I worked on the tool itself, not just as its user.

Down to the metal
A game engine written from scratch — renderer, physics integration and scene handling. A pathtracer with light transport implemented by hand: the theory behind every frame an engine gives you for free. A real-time fluid simulation. Breakout written natively in C++ on Android. This is the same shader instinct I now apply in HLSL on Quest.

Web prototypes
MY OWN PROTOTYPES — NOT CLIENT WORK
A league platform for 34 teams and an events agenda for two music venues, both for people I know. Pitched, never contracted, never in production. AI-built, with me as engineer and functional definition.
