  • CalFresh Healthy Living - Automation Applications

    A suite of SharePoint online hosted modern web applications built in React and TypeScript which 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 along with reporting to the federal government.

  • RxSource 360

    A healthcare-related data analytics and reporting application.

    I was the technical lead and architect on the project, hired because the client was migrating a legacy ASP application and wanted to use Microsoft Silverlight for the front end.

    Although I was originally hired for front-end development only, I soon replaced the original architect who was underperforming and took over the project development and architecture. I quickly re-architected the solution, set up Visual Studio Projects and Solution, and finished designing and developing the entire database. Using OOB frameworks from Microsoft such as Entity Framework and Silverlight's Web API framework (RIA Services), the team developed features at a much faster pace.

    Stakeholders were very pleased and after 1.5 years, the entire application was developed and launched. Aside from the front-end application, Web APIs, and databases, the solution required Message Queue technology (Microsoft MSMQ) in order to handle report requests, which could be scheduled or run on-demand. The messages were sent to the web API once the server was able to handle the request and would generate the report. I was later re-hired to rewrite the front-end in WPF.
