Worked on the Sundsvallskommun/api-service-invoice-sender repository, focusing on maintaining system stability and ensuring reliable invoice processing. Addressed a dependency issue by rolling back the Jsoup library to version 1.19.1, which resolved problems introduced by a recent update without requiring any changes to the existing Java codebase. Emphasized careful dependency management and risk mitigation within the CI/CD workflow, documenting the rollback process for traceability. The work prioritized downstream compatibility and operational continuity, demonstrating a methodical approach to release hygiene. Utilized skills in Java, Maven, and continuous integration to maintain the integrity of the invoice-sending service during this maintenance cycle.
