Graphics Software Engineer specializing in real-time rendering, GPU optimization, and engine tooling. I've scaled crowd rendering pipelines from 150 to 10,000+ characters at 60 FPS, rebuilt scientific visualization systems from 20 to 120 FPS on Unreal Engine 5, and built a physically-based path tracing engine from scratch with OpenGL and Vulkan backends. Four years of professional C++ across simulation, VR, and industrial software. I find the real bottleneck CPU, GPU, or architecture and fix it at the root.…Graphics Software Engineer specializing in real-time rendering, GPU optimization, and engine tooling.

3D Software Engineer at Sogeclair (Oktal SE)

November 1, 2025 - Present

Optimized a crowd rendering pipeline from ~150 animated characters at 30 FPS to 10,000+ characters at 60+ FPS in real time using GPU hierarchical instancing and vertex animation textures. Reverse-engineered an undocumented legacy AI/crowd simulation system (~60,000 lines), producing architectural documentation to enable long-term extension and maintenance. Built a C++/Qt plugin for automatic NavMesh generation (Recast) using spatial partitioning for large-world AI pathfinding under tight subdivision constraints. Developed a Blender Python plugin to automate VAT and skinning matrix baking for the character pipeline. Implemented a multi-screen display deployment solution in Unigine.

R&D Software Engineer (Scientific Visualization & VR) at LeCNAM (Scientific Visualization & VR)

December 1, 2022 - September 30, 2025

Rewrote a real-time scientific visualization codebase in C++ on Unreal Engine 5, improving performance from ~20 FPS to ~120 FPS and adding iso-surface, glyph, and streamline rendering modes. Built a pipeline processing 50M+ data points in ~8 ms (Core i9-12900HK, NVIDIA 3070). Designed a TCP/UDP network interface linking a CFD solver (2× NVIDIA H100) to an immersive VR visualization app using multi-resolution streaming and controlled latency. Implemented Marching Cubes (C++/HLSL) for iso-surface extraction and mesh simplification/LOD management. Optimized VR rendering with polygon reduction, texture compression, overdraw detection, and tuned distance culling for sustained real-time frame rates. Created a cross-platform shared library (DLL/SO) for code reuse between the solver interface and the UE5 application (Linux/Windows).
