During May 2025, contributed to the LunarG/gfxreconstruct repository by developing the Selective Application Tracing feature, which enables targeted tracing of a single application in environments where multiple applications, including those using Vulkan, are running concurrently. This feature was implemented in C++ and leverages system programming and multithreading techniques to allow users to specify an application by name, thereby focusing trace capture and reducing extraneous data. The approach streamlines debugging by minimizing noise and improving analysis efficiency. The work established a foundation for future enhancements, emphasizing maintainability and traceability through clear commit history and reproducible implementation practices.
