PROFILE
Maciej Sabat
Worked on the allegro/hermes repository to deliver automated performance benchmarking and reporting for backend systems. Developed an end-to-end JMH benchmarking capability for the Hermes consumer, establishing measurement discipline and improving performance visibility. Extended benchmarking to support message filtering and enhanced reliability through parameter tuning and comprehensive documentation. Leveraged Java, Gradle, and JMH to implement these features, while integrating GitHub Actions workflows for continuous integration. Automated the generation and comparison of performance reports across branches and ensured reliable publication of test results to the gh-pages subfolder. This work accelerated feedback loops and improved accessibility of performance data for stakeholders and teams.
