During November 2024, Truc Le Ngoc enhanced workflow stability and data integrity across the ncc-erp/ncc-erp-workflow-w2-ui and ncc-erp/ncc-erp-workflow-w2 repositories. Truc developed a NumericField React component in TypeScript to standardize numeric input handling and validation in forms, addressing previous inconsistencies. To prevent modal crashes, Truc introduced input definition validation and user-facing warnings, improving error handling in the workflow UI. On the backend, Truc resolved a bug that previously caused published workflows to become unpublished during updates by ensuring the IsPublished flag was preserved. The work demonstrated solid backend and frontend engineering with a focus on reliability and maintainability.
