Worked on the atlassian-labs/compiled repository to deliver a security and performance-focused dependency upgrade. Addressed vulnerabilities in the legacy CSS implementation by migrating to @adobe/css-tools, which also improved build speed and reduced maintenance risk. Upgraded the Node.js environment to a supported version, ensuring ongoing compatibility and access to updates. The work centered on front end development, leveraging skills in CSS, Node.js, and JavaScript to enhance the reliability of continuous integration workflows. No separate bug fixes were reported during this period, as the primary focus remained on optimizing dependencies and infrastructure for better long-term project stability and maintainability.
