Led AR/VR and multiplayer feature development on projects spanning military and e-commerce domains across multiple platforms
Key Contributions:
• Reduced WebGL build size by 57% (35 MB > 15 MB), significantly improving load times and enabling broader device compatibility for mobile AR users
• Optimized AR tree mesh using Speed Tree, cutting triangle count by 62% (84k > 32k) without visual quality loss• Lowered memory usage of tree mesh growth animation by 45% (28 MB > 15 MB), boosting runtime performance significantly on mobile
• Built a hybrid, platform-adaptive AR solution using a dual-plugin strategy (WebXR Export & Imagine World Tracker), ensuring seamless cross-platform support on iOS and Android WebGL
• Implemented QR code scanning via Zxing.net, boosting input flexibility and enhancing security in mobile AR e-commerce experiences
• Engineered a robust real-time client-host architecture for a realistic military-grade VR shooter, syncing Meta Quest 3 and Windows clients via Photon Fusion using RPCs, networked components, and property replication
• Built a full-featured realistic ballistics system with wind-influenced projectile physics and synchronized VFX/SFX across VR and desktop platforms
• Created modular shooting exercise analytics pipeline, from extensive real-time UI feedback to printable HTML reports and persistent archives, streamlining military instructors’ session analysis

Executed full-cycle features for driving simulation and shooter games targeting Windows and PS5, independently working within a large cross-functional outsourcing team
Key Contributions:
• Built dynamic, impact-responsive vehicle part detachment system, enhancing crash realism in a first-person 3D driving simulator
• Developed full-cycle vehicle interaction system: NWH Vehicle Physics 2-powered driving, contextual character entry/exit triggers, and perspective-switchable camera views
• Engineered a step-by-step tutorial with dynamic input gating, progressively unlocking controls through guided, target-based shooting sequences for intuitive player onboarding
• Implemented contextual footstep audio system linked to terrain surfaces and movement states (e.g., sprinting on gravel, crouching on grass, etc.), enhancing environmental immersion and player feedback
• Delivered immersive shooting and hit detection mechanics using Realistic Sniper and Ballistics System, featuring body-part-based damage with tiered rewards, weapon-dependent behavior, and cinematic slow-motion bullet flight animations
• Developed a highly customizable modular animal AI system powered by Malbers Animal Controller, featuring dynamic animation blending, behavior-state logic, and proximity-triggered SFX to simulate lifelike wildlife interactions
• Built platform-adaptive UI/UX for PS5 and Windows, featuring intuitive navigation for both gamepad and mouse users, a filterable shop for weapon models and skins, and persistent audio and graphics settings
