Tyler Technologies, Software Engineer Professional

  • Helped build configurable Workflow Tracking and BPM software systems using the company's entellitrak platform.
  • Lead development on a baseline Background Investigations system equipped with common BI application functionality which has been used to help reduce the time needed to produce a client-ready application. Among other things, the system is able to:
    • Track cases throughout the lifecycle of an investigation
    • Ingest files created by outside government agencies which contain data that can be used to create new cases in the system or update existing case data
    • Produce standardized files that summarize the status of investigations and clearances in the system which are then transmitted to outside government agencies
  • Developed a timekeeping module used by multiple systems to track their investigators' working hours. The module works in compliance with Law Enforcement Availability Pay (LEAP) federal regulations.
