Worked on stabilizing currency management within the upstars-global/cardona-core-service repository by reverting a high-impact change that had affected core service behavior. Addressed a critical bug by restoring pre-change currency handling, ensuring consistent and reliable currency state across multiple projects. Simplified state management by removing project-specific currency lookups in Vuex getters, opting instead for direct use of stored values. This approach improved pricing accuracy, reporting reliability, and reduced maintenance complexity. Demonstrated strong skills in TypeScript, API integration, and state management while maintaining clear commit traceability and minimizing user disruption during the rollback process across the codebase during May 2025.
