Denis Dubin

Technical Supervisor / Technical Artist at Victoria VR

Designed and implemented SDK-like profiling tools: automated scene profiler, Material Auditor for shader efficiency. Optimized VR projects from under 30 FPS to 90 FPS, addressing GPU/memory bottlenecks — directly analogous to mobile optimization. Reduced asset pipeline errors by creating efficiency editors for batch validation and data consistency. Architected plugin-based pipelines integrating C++ and Python to extend Unreal Editor functionality. Mentored developers, enforced coding standards, and ran design/code reviews. Key achievements include delivering tools/workflows matching Playrix needs: content editors, profilers, performance SDK-like systems. Tools & Open Projects included UE5 Toolbox Plugin with scene profiler and material audited editor for automated performance reporting; UE4 Profiler modular plugins & pipelines combining C++ + Python for UE Editor automation.

Built and optimized core Unreal Engine gameplay systems (combat, movement, progression, and save/load). Implemented multiplayer features with replication, authority logic, and server-side validation. Implemented telemetry and heatmap tracking for balancing and QA. Optimized Unreal levels, achieving up to +200% FPS in demanding scenes on PC and standalone VR. Created editor tools and automation pipelines (Python-based) to streamline workflows; reduced manual QA/validation workload by 25%+. Collaborated cross-functionally to deliver prototype and production-ready features; delivered VR interaction systems and UI. Extended Unreal with Python automation pipelines.
