During May 2025, Dejan focused on improving the trustification/trustify-ui repository by addressing a bug related to vulnerability CVSS filtering. He updated the search logic to use the base_severity parameter instead of average_severity, ensuring the UI accurately reflected the new API’s risk scoring model. This adjustment improved the precision of vulnerability data displayed to security teams and reduced the risk of misrepresented scores. Dejan validated the end-to-end filtering and display alignment, maintaining awareness of the API contract and regression readiness. His work leveraged front end development skills with React, utilizing both JavaScript and TypeScript to implement and test the solution.
