PROFILE
Aaron Barany
Worked on core systems in both the google/flatbuffers and jrouwe/JoltPhysics repositories, focusing on code generation hygiene and performance optimization. Improved the FlatBuffers Python code generator by preventing the creation of empty output files and removing obsolete test artifacts, which streamlined repository maintenance and enhanced downstream build reliability. In JoltPhysics, optimized quaternion multiplication using SSE and FMA instructions, restructuring algorithms for better computational efficiency in physics simulations. Also introduced a CMake build flag to support both static and shared library builds, increasing deployment flexibility. Demonstrated expertise in C++, CMake, and performance tuning for computer graphics and build systems.

2 Commits • 2 Features
Mar 1, 2026March 2026 – Key features delivered in jrouwe/JoltPhysics: 1) Physics Engine: Quaternion Multiplication Performance Optimization (SSE/FMA) to reduce instruction count and leverage FMA; 2) Build System: Introduce JPH_BUILD_SHARED_LIBS for static/shared libs, boosting packaging and deployment flexibility. Major bugs fixed: none reported. Impact: measurable performance uplift in physics simulations and easier embedding in host projects. Technologies/skills demonstrated: SIMD optimization (SSE), FMA usage, build system configuration (CMake), algorithm restructuring for efficiency.

Jun 1, 2025June 2025: Focused on code-generation hygiene for google/flatbuffers. Implemented a cleanup to stop generating empty Python files when a type has no structs or enums, and removed several obsolete test Python artifacts. These changes reduce output clutter, prevent accidental overwrites, and improve downstream build reliability for Python consumers. The work enhances developer productivity and repository cleanliness while maintaining compatibility with existing codegen workflows.
