Dominik Arnold developed core profile management features for Axon Ivy, focusing on both user and admin workflows across the dev.axonivy.com and engine-cockpit repositories. He implemented JSON-based updates for team member profiles, enhancing data accuracy and user experience. For admin users, he built a profile management page using JavaServer Faces (JSF) and PrimeFaces, introducing view and edit capabilities, UI refinements, and load optimizations. Dominik expanded Selenium-based UI testing to ensure reliable navigation and behavior. His work addressed data handling, optional email fields, and deprecated element removal, resulting in more robust, maintainable front-end and backend profile management functionality.
