Worked on stabilizing cross-platform build and rendering systems in open-source C++ projects, focusing on the rerun-io/rerun and flutter/flutter repositories. Addressed Windows build failures in rerun_cpp by updating CMake export configurations to include necessary Windows-specific libraries, enabling reliable external linkage and improving cross-platform compatibility. In the Flutter Impeller Vulkan backend, implemented logic to correctly recreate Vulkan transients when surface sizes change, reducing rendering glitches during window resizing. Added regression tests and documentation to ensure correctness and maintainability. Utilized C++, CMake, and the Vulkan API, emphasizing robust build systems, graphics programming, and thorough unit testing to enhance project stability.
