During June 2026, contributed to the facebook/igl repository by implementing Vulkan timestamp queries for GPU timing, enabling precise measurement of GPU operations within the rendering pipeline. This feature allows developers to profile and optimize rendering performance by providing detailed observability of CPU-GPU timing interactions. The work involved graphics programming and performance instrumentation using C++ and the Vulkan API, with a focus on integrating timing queries seamlessly into existing workflows. Collaboration was demonstrated through code reviews and approvals, ensuring code quality and maintainability. This addition laid the groundwork for broader adoption of performance profiling tools within the igl rendering stack.
