  • US Department of Health and Human Services – Served as lead developer for a new grant award notification system. Grants are sent in flat files to the operators who load using an APEX front end. The system steps them through the process of correcting errors and assigns each grant to a congressional district. The operators then select the grants they wish to send notices for and the system emails the appropriate Congressional staff.
  • Florida Department of Health – Worked as sole developer to create a website for defining and administering online surveys. Survey designers can choose from several different predefined metrics or create new ones. Questions can be grouped in grids when they share the same Likert scale. Questions can also include logic that determines if they should be shown or hidden based on other responses, how many choices can be marked, and the required total among a group of numerical responses. This logic is implemented on the survey pages by javascript that registers events and handlers that read the definitions from JSON objects.
