In March 2026, Alexei Kondratenko integrated gperftools version 2.18.1 into the bazelbuild/bazel-central-registry repository, delivering a new profiling capability for Bazel users. He developed a Bazel module with precise dependency management and configuration, enabling seamless use of gperftools for performance analysis during builds. The work involved authoring and validating JSON and Bazel configuration files, ensuring compatibility with the existing toolchain. By focusing on module integration and configuration optimization, Alexei addressed the need for advanced profiling support in Bazel, enhancing build-time performance analysis without introducing regressions. This contribution demonstrated depth in Bazel, dependency management, and module configuration.
