Alkiviadis Zaganiaris developed a Team Management Schema Enhancement for the theopensystemslab/planx-new repository, focusing on improving how team members are added and managed within List and Page components. Using React and TypeScript, Alkiviadis designed a reusable data model that supports structured team information, laying groundwork for future features like permissions and roles. The schema was integrated into existing UI flows with minimal disruption, streamlining data entry and enhancing data integrity across components. This work emphasized schema design and component integration, resulting in a more scalable and governance-ready foundation for team management without introducing major bugs during the development period.
