PROFILE

Fabien Péan

Worked across NVIDIA/warp, microsoft/vcpkg, and Xiangyu-Hu/SPHinXsys repositories to deliver robust features and targeted fixes in C++ and Python. Enhanced NVIDIA/warp by enabling indexed arrays within structs and introducing union type annotations for Warp arrays, improving data modeling and type safety in CUDA kernels and Python interfaces. Upgraded OpenVDB support in microsoft/vcpkg, refining build systems and CI for reproducible, compliant deployments with CUDA and NanoVDB integration. In SPHinXsys, strengthened geometric computations by hardening bounding box calculations and resolving SYCL compilation issues. Demonstrated a disciplined approach to kernel development, metaprogramming, and testing, with a focus on reliability and maintainability.
