The application consolidates data from various internal and external applications to give users a single view of a customer's 911-related data. System reduced average handling time by more than 90% and has a component which automatically compares data to identify issues. Application is developed using Java EE using JSP, Primfaces, JPA, Javascript and Oracle 11g database. Microservices are used to retrieve data using SOAP and REST web services and web screen scraping. Application use WebLogic JMS queues and Java threading is able to process large volumes of data in parallel.• Developed a network issue management system and migrated from a legacy application. System is processing several hundred thousand records per day and automatically identify issues which require user resolution. The application further allows users to schedule and oversee batch processes. Application was developed in Java EE using JSP, Primefaces, JPA and Oracle 11g database. Resolved performance issues by introducing database set-based pre-processing and use of Java threading which improved performance by up to 100 times. Show less
