Worked on the dotnet/performance repository to deliver and standardize a GC Performance Benchmark Environment Configuration, focusing on improving the reliability and efficiency of garbage collection benchmarks. Updated environment variables to adjust GC heap limits and server mode, enabling more representative and repeatable performance testing scenarios. This configuration management effort reduced setup friction and variability, supporting data-driven optimization of .NET garbage collection behavior. Leveraged skills in benchmarking, configuration management, and performance testing using C# to automate and refine the testing environment. The work enabled faster, more accurate performance assessments and provided clearer guidance for future optimization efforts within the repository.
