PROFILE
William Schlegel
Worked on the checkmarble/marble-frontend repository to deliver a broad set of user-facing features and stability improvements over four months. Focus areas included scenario management UI overhauls, robust data modeling workflows, and enhanced screening processes. Leveraged React, TypeScript, and Vite to implement accessible interfaces, advanced state management, and modular component design. Addressed data integrity by enforcing validation and deduplication, while improving localization and error handling for multi-language support. Refactored internal tooling and upgraded dependencies to streamline development and deployment. The work resulted in faster, more reliable workflows for users, improved data quality, and a maintainable, modernized frontend codebase.
