Worked on the h2oai/h2o-3 repository to enhance build reliability and prevent API configuration contamination by refining benchmarking integration. Addressed a leak in u-benchmarks and implemented an opt-in approach for benchmarking dependencies, ensuring that JMH is included only in specific modules when the doUBench property is explicitly enabled. This adjustment reduced the risk of unintended dependency injection across the multi-module project and improved continuous integration stability. Utilized Gradle for build automation and dependency management, focusing on aligning benchmarking tools with explicit configuration. The work contributed to cleaner build hygiene and more predictable release quality without introducing new features during the period.
