P R O F E S S I O N A L S U M M A RY

Senior UE5 Systems Architect & C++ Engineer with 8+ years of commercial experience building server-authoritative
multiplayer infrastructure, proprietary graphics systems, and high-load backends. Architected Docker-orchestrated
dedicated server pipelines capable of managing 50+ concurrent UE5 instances. Delivered stable 72 FPS on Meta
Quest 3 under a strict 13.8ms frame budget through custom RHI/Vulkan optimizations. Highly proficient in low-level
C++ gameplay math and HLSL shader optimization. Currently acting as the primary technical architect for Play
Fusion Labs, delivering end-to-end UE5 solutions for incoming enterprise clients. Available for remote B2B
contracts.

PROFESSIONAL EXPERIENCE

Play Fusion Labs
Jan 2023 – Present
LEAD UE5 SYSTEMS ARCHITECT (CONTRACT)

Acting as the primary technical architect for incoming enterprise clients, collaborating with Project Management to
deliver complex end-to-end UE5 solutions.

Project: Cloud-based Pixel Streaming Platform Feb 2025 – Present

- Infrastructure & Security: Identified DDoS/Cloudflare risks in ephemeral cloud instances. Architected a secure
Web-to-UE "Token Handshake" to propagate JWT tokens via launch parameters, bypassing direct IP blocks.

- REST API & DX Toolkit: Engineered an asynchronous C++ authentication framework. Built a reusable Blueprint
API library with automatic token injection and UI-level rate-limiting, allowing UI artists to integrate backend
endpoints safely without touching C++.

- Performance: Handled complex JSON parsing with custom UJSONWrapper classes, achieving zero memory
leaks and preventing UI thread blocking.
Project: B2B VR Training Simulator for Meta Quest 3 Jan 2023 – Jan 2025

- Mobile VR Optimization: Achieved a stable 72 FPS on Meta Quest 3 (Android Vulkan) rendering high-poly
MetaHuman assets, delivered under a strict 13.8ms frame budget.

- Custom Volumetric Clipping: Engineered a custom C++ voxel 3D masking system to bypass native UE Groom
limitations on mobile hardware, enabling real-time dynamic interactions unavailable out of the box.

- RHI State Serialization: Implemented real-time Undo/Redo mechanics via low-level 3D Render Target
serialization (preserving RHI texture states directly into memory).

- Data-Driven Architecture: Decoupled interaction logic from rendering by splitting the architecture into State,
Tool, and Presentation layers.

Last Art Studio (Proprietary MMO Framework)
Mar 2022 – Present
LEAD SYSTEMS ARCHITECT

LA:FO (Multiplayer Flight Combat)

- High-Load Orchestration: Designed a backend capable of orchestrating 50+ concurrent UE5 Dedicated Server
instances via the Docker Engine API with dynamic spin-up and load balancing.

- Network Engineering & DPI Bypass: Engineered a Dual-Plane network: combat traffic via UDP (Epic Online
Services) and meta/control traffic via a custom C++20 coroutine WSS Tunnel (SOCKS5 over WebSocket)
masking through Cloudflare CDN, successfully solving DPI blocking issues.

- Data Compression (Bitpacking): Reduced equipment replication payload by ~70% via custom bitwise
operations—compressing a full Combat Manifest into a 16-byte matrix.

- Advanced C++ Gameplay Math: Developed custom UActorComponent architectures for procedural vehicle
and weapon control. Authored math libraries handling quaternions, spatial transformations, and predictive
aiming (lead calculation) with network interpolation and gimbal lock prevention.

- UI Pipeline & HLSL Optimization: Designed and currently implementing a highly performant React-to-UE5
(UMG/Slate) integration pipeline. Engineered custom HLSL shaders and procedural UI materials to drastically
reduce VRAM overhead and draw calls.

Likater Studio
Jan 2025 – Mar 2026
UNREAL ENGINE DEVELOPER

Project: Lyrvane Park (Core Dev & Release Prep)

- Gameplay Engineering: Implemented gameplay systems, architecture logic, and Blueprint-based mechanics
including complex puzzle interactions and environmental behavior.

- Production Integration: Contributed to active prototyping, debugging, and QA within a structured production
team environment, successfully delivering logic for a commercial Steam release: Lyrvane Park on Steam.
