Worked on protocolbuffers/protobuf and libsdl-org/SDL, focusing on cross-platform stability and hardware integration. Addressed a .NET AOT compatibility regression by replacing Marshal.SizeOf(typeof(T)) with the generic Marshal.SizeOf<T>() in C#, improving type size consistency and reducing runtime risk for Ahead-Of-Time compiled targets. In the SDL repository, delivered a feature expanding PS5 controller LED indicators to support additional player indices, enhancing multiplayer feedback and maintaining backward compatibility. Demonstrated expertise in .NET Core, C, and embedded systems, with careful attention to regression risk, cross-platform behavior, and low-level driver logic to deliver targeted, reliable improvements for downstream users.
