Optimization tooling and engine plugins for an unannounced project.

• Developed high-performance Unity and Unreal Engine plugins that communicate with internal optimization tools.
• Replaced JSON with a compact binary protocol, cutting inter-process communication bandwidth by about 32%.
• Reviewed profiling reports for games moved from PC to mobile and found gaps, such as a major studio's mobile engine missing frustum culling.
• Co-authored a patent application on novel techniques for improving rendering performance.
• Built a plug-and-play performance optimization toolset selected for integration into an upcoming Samsung flagship device.

Unreal Engine 5 rendering and UI for Apple Vision Pro.

• Led the investigation of alpha holdout blending in UE5 on Apple Vision Pro, using RenderDoc to find mobile rendering pipeline limits for transparent elements in mixed reality.
• Found that multi-pass transparency, which blends separate opaque and translucent buffers, worked on Windows and Mac but was unsupported on visionOS, iOS and Android.
• Built a pipeline that passes ASTC-compressed textures from Unreal Engine to the native visionOS renderer, cutting VRAM use by 40%.
• Modified Unreal Engine source so UMG designs are replicated in the native UI framework, enabling Vision Pro eye-gaze and pinch input.
• Implemented face-lock behaviour for RealityKit entities using its ECS.

Engine, gameplay and build-size work across three projects in Unreal Engine and C++.

Unity games for international clients.

• Developed multiple Unity games, implementing gameplay mechanics and third-party SDK integrations.

A C++20 game engine with a hand-written Vulkan 1.3 renderer.

• FBX meshes loaded from disk and uploaded to the GPU
• Pipeline cache keyed on shader pairs
• ECS rotate system
• Perspective camera (left-handed, Z-up)

A top-down game with its own rendering pipeline for PlayStation 5 and Windows.

• Cross-platform rendering pipeline for PlayStation 5 (AGC, PSSL) and Windows (OpenGL, GLSL)
• Deferred lighting added to the existing PBR system, with 64 GPU-instanced point lights and 1 directional light
• Instanced repeated objects such as walls and bounce pads, cutting draw calls by 42% (550 to 315)
• Graphics debugging with NVIDIA Nsight Graphics and Razor GPU

A physically based, deferred rendering pipeline written from scratch.

• PBR pipeline written by hand in C++, OpenGL and GLSL
• Deferred rendering, informed by a study of the GTA V rendering pipeline
• Directional, spot and point lights
• Reinhard tone mapping and gamma correction as post-processing

A real-time stylized scene with GPU instancing, culling and cel shading.

• GPU instancing draws whole forests of trees in a single draw call
• CPU frustum culling with bounding-sphere tests
• Deferred rendering with specular lighting
• Post-processing in GLSL: saturation, desaturation and blur
