I'm a Senior Unity XR Engineer with 8+ years building immersive applications that ship, not prototypes that stall at 90% done.
What I've delivered on Upwork:
My largest engagement is a VR game project I've led since 2024: 12 interactive levels with dynamic state systems, built for Meta Quest standalone, 6,400+ hours and $240K+ billed on a single contract. The client's review: "One of, if not the best developer(s) I've ever met."
Alongside that: a HoloLens 2 mixed reality CPR training simulation, custom VR combat and interaction systems, and multiplayer VR builds.
Where I'm strongest:
Meta Quest standalone performance, holding frame budget on mobile-class hardware, where most XR projects fall apart
Custom interaction systems built on Unity XR Toolkit
Mixed Reality passthrough and spatial anchoring (HoloLens 2, Quest 3)
Multi-scene architecture and state-driven systems that survive handover to another team
Simulation and training environments, medical, industrial, educational
Platforms: Meta Quest 2 / 3 / Pro, HTC Vive, HoloLens 2, AR Foundation (ARKit / ARCore), PC VR
How I work: I respond within a few hours, I tell you upfront if your scope doesn't match your budget, and I don't disappear mid-project,the 6,400 hours on one contract are the evidence.
Send me your target headset and rough timeline and I'll come back with an honest read on whether it's a two-week build or a two-month one.
