PROFILE

Nicolas Vannier

Worked on the eclipse-sirius/sirius-web repository to deliver two core features enhancing diagram editor usability and customization. Developed a persistent diagram appearance management layer, enabling end-users to customize and restore diagram element styles, with backend storage and frontend tooling for applying and saving changes. Authored architectural documentation to guide future governance of appearance management. Later, implemented a bulk delete capability for diagram elements, streamlining batch operations and reducing repetitive user actions. Leveraged TypeScript, Java, and Playwright for robust frontend and backend development, state management, and automated testing. The work focused on maintainability, user experience, and aligning with product goals for productivity.
