Big Cash Poker had a 50M+ user mobile base and a proprietary Java backend built for mobile traffic rather than real-time XR. Extending it into VR required a Unity client to meet tighter latency requirements and ship in three months.

What I built

I led end-to-end Unity development of the multiplayer Meta Quest experience: real-time multi-user game logic, networked interactions, and 3D rendering on standalone hardware. The core engineering work was integrating the Unity VR client with the Java backend and optimizing state synchronization for concurrent sessions. I also ran device testing and frame-rate profiling on Quest 2 and Quest Pro, and established the Agile sprint and code-review process used by the team.

Outcome

Shipped in 3 months with sub-100ms multiplayer latency and zero critical post-launch defects for a 50M+ user platform. The Agile and code-review process reduced delivery time by 25%.
