Worked on the Unity-Technologies/InputSystem repository to enhance performance profiling capabilities within the Unity Input System. Focused on implementing ProfilerMarkers using C# to measure the performance of enabling and disabling InputActions as well as resolving input bindings. Integrated these markers directly into core InputSystem methods, enabling more granular and accurate performance analysis. This technical approach established a foundation for data-driven optimization and facilitated faster diagnosis of performance issues. Leveraged expertise in C#, performance profiling, and the Unity Input System to deliver instrumentation that supports ongoing improvements in input handling efficiency and maintainability, addressing a key need for robust profiling tools.
