Worked on stabilizing drift axis handling within the TPC geometry utilities in the SBNSoftware/icaruscode repository, focusing on compatibility with v10 geometry updates. Addressed a regression by refining the conditional logic in TPCGeoUtil.cc, ensuring the function returns 0 only when the drift axis is not X, thereby preserving correct drift direction handling. This targeted bug fix improved data reliability and prevented drift-related processing errors in downstream analyses. Demonstrated proficiency in C++ and geometry utilities, applying a focused bug-fix workflow and version control practices. The work contributed to maintaining the integrity of physics results in environments dependent on accurate geometry processing.
