Worked on the SBNSoftware/sbndcode repository to enhance the stability and reliability of the PTB analysis pipeline. Focused on debugging and build system improvements using C++, addressing a critical initialization error in PTBAnalysis_module.cc that previously caused compilation failures. The solution involved correcting a variable naming inconsistency, which restored successful builds and ensured the PTB analysis module functioned as intended. This fix was verified through both local builds and continuous integration, reducing the risk of future analysis downtime. The work improved code maintainability and reliability, supporting smoother downstream data processing and reinforcing robust development practices within the project’s C++ codebase.
