Top Rated Plus | 100% Job Success | $200K+ earned on Upwork | 6,400+ hours on production XR builds 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.
