Developed and integrated the gperftools 2.18.1 module into the bazelbuild/bazel-central-registry repository, enabling enhanced profiling capabilities for Bazel users. The work involved configuring Bazel modules, managing dependencies, and optimizing module configuration to support seamless profiling with gperftools. Using Bazel and JSON, the developer ensured that the new module was properly validated and committed, allowing users to leverage improved performance analysis tools within their build workflows. This contribution strengthened toolchain compatibility with the latest gperftools release and provided a foundation for more effective build-time performance diagnostics, reflecting a focused approach to dependency management and configuration optimization.
