Worked on the SPM587FA24/SCM587FA24 repository to address identifier validation issues within Java-based workflows. Focused on resolving a bug by updating the allowed identifiers list in s.java, ensuring that the new identifier SFA23SCM37MA would be correctly recognized during validation processes. This change improved the consistency and reliability of identifier handling across end-to-end workflows, reducing the risk of misrecognition and supporting compliance requirements. Demonstrated skills in Java and code addition, while following established issue tracking and code review practices. The work contributed to the stability of runtime workflows by enhancing the robustness of validation logic without introducing new features.
