Physics, Graphics & Tools Programmer. I mostly live in Unreal Engine (C++), with a solid Unity background from earlier projects.

I like the parts of development most people usually skip past: memory layout, why a frame drops, how a shader actually maps to the render target. My favorite kind of bug is the one that only shows up because you understood the system.

I mostly work with Modern C++, engine architecture and real-time graphics (Unreal Engine, OpenGL), with a solid background across interactive systems.

• Real-time physics & simulation: SPH fluid simulation from scratch, moved from a CPU/ECS solver to a GPU compute pipeline once particle count made the CPU path the bottleneck. FluidSimulationECS
• Unreal Engine (C++): Gameplay systems, event-driven architecture, and a custom 3D gravity/physics system for End of Life (PlayStation Talents Finalist).
• Rendering & shaders: GLSL/HLSL, OpenGL pipelines, render textures, frustum culling and the usual GPU-vs-CPU tradeoffs that come with real-time particle work.
• Tools & pipelines: Unity to Unreal migrations, editor tooling and the less glamorous work of making a team's workflow not fight them.

• Languages: C++, C#, GLSL/HLSL, Lua
• Graphics & Simulation: OpenGL, Vulkan (Foundations), RHI/Compute Shaders, ECS/DOD
• Engines & Tools: Unreal Engine (C++/Blueprints), Unity, RenderDoc, NVIDIA Nsight, CMake, Git
