Worked on the Jahia/jcontent repository to deliver a user experience enhancement for Work In Progress (WIP) content marking. Updated the labeling logic in the React-based front end to improve the accuracy of content status indicators, addressing challenges with mislabeling and streamlining the content review process. Developed and integrated automated tests using JavaScript to validate WIP state transitions, ensuring both typical and edge-case scenarios were covered for regression safety. This feature improved collaboration and governance by accelerating review workflows and reducing errors. All changes were maintained with clear code traceability, reflecting a focus on robust, test-driven front end development practices.
