In February 2026, Ilarin contributed to the JeffersonLab/halld_recon repository by implementing a TimeBased Track Selection feature within the JEventProcessor_cpp_skim module. This work replaced the previous WireBased approach, introducing more flexible and tunable criteria for track selection in event processing. Using C++ and leveraging data analysis and event processing skills, Ilarin refactored the module to relax selection constraints, enabling improved throughput and maintainability. The update was carefully documented to align with the project’s reconstruction roadmap, supporting future experimentation and optimization. This contribution demonstrated thoughtful engineering depth and collaborative development practices within a complex scientific codebase.
