This software reuse saved the office 6+ months of precious developer resources and jump-started their effort to better track work-related metrics.
  • Developed, tested, documented, and implemented web applications that allowed the customer to store and report their operational successes and employee information. These custom applications saved the office 10+ staff hours per week answering metrics-related questions from their chain of command.
