Michael O’Brien developed end-to-end job application deletion features and dashboard enhancements for the tracker-crm and tracker-crm-fe repositories. He implemented secure backend deletion flows in Ruby on Rails, enabling both user self-deletion and admin workflows, and updated routing, controllers, and policy authorization to support these changes. On the frontend, he built a React-based UI for job application deletion, integrating comprehensive Cypress and unit tests to ensure reliability. His work also included dashboard improvements with accurate data rendering and empty-state handling. Throughout, Michael maintained thorough documentation and test coverage, demonstrating depth in JavaScript, TypeScript, and API development while improving data hygiene.
