Worked on the LunarG/gfxreconstruct project, focusing on improving the reliability and accuracy of DirectX 12 capture and replay workflows. Addressed stability issues by validating function pointers, adding debug logging, and implementing null checks to prevent crashes during D3D12 replay. Enhanced replay fidelity by restructuring ID3D10Blob processing and introducing support for shared resource operations, ensuring correct ordering and robust resource management. Utilized C++ and Python to refactor code, debug complex graphics scenarios, and extend API replay capabilities. The work emphasized careful state tracking and software architecture improvements, resulting in more dependable debugging and reproducible graphics capture scenarios for developers.

Aug 1, 2025August 2025: Key bug fix and reliability improvements for gfxreconstruct focusing on ID3D10Blob replay processing. Implemented a two-pass processing order (root signature blobs first, then cached PSO blobs) to ensure correct ordering and prevent premature writes of cached PSOs, improving replay accuracy across captures and reducing debugging effort.

Apr 1, 2025April 2025 (LunarG/gfxreconstruct): Delivered stability improvement for D3D API callback replay by validating/correcting function pointers and adding debug logging when callbacks are invoked. The change reduces replay crashes on complex D3D workflows and improves diagnosability without impacting existing replay behavior. Prepared groundwork for broader D3D callback coverage and reinforced the reliability of the D3D replay pipeline.
