Experience
CalFresh Healthy Living | Automation Applications
A suite of SharePoint Online hosted modern web applications—built in React and TypeScript—and are managed by the California Department of Social Services agency.
The applications are used by internal and external users throughout California and hosted in Microsoft 365 environment. Users originally managed their content using multiple Microsoft Word documents and Excel files, which proved problematic. The new applications have streamlined data entry using modern web forms and greatly increased user efficiency and reporting to the federal government.
