Worked on the RNO-G/mattak repository to establish foundational support for data compression in C++-based data pipelines. Focused on integrating compression headers and aligning output file creation with the ROOT 6.36 API, the work ensured that compression algorithms are specified correctly to prevent misconfiguration. This approach enables future enhancements for compression-enabled workflows and maintains compatibility with evolving system requirements. Leveraged skills in build systems, system programming, and C++ to implement these changes, applying targeted commits to update the codebase. The contribution addressed API compatibility and set the stage for more robust data handling without introducing new bugs or regressions.
