Worked on the awslabs/mountpoint-s3 repository to refactor the benchmark script, introducing a configurable debug mode controlled by an environment variable. This update consolidated the read and write benchmark logic, reducing code duplication and streamlining the execution flow while maintaining the core benchmarking functionality. The approach focused on improving maintainability and reproducibility of performance tests, supporting safer experimentation in both development and CI environments. The work was implemented using shell scripting and benchmarking techniques, with an emphasis on scripting best practices. No bug fixes were required during this period, as the primary goal was to enhance code quality and reliability.
