Contract Rate Implementation Transformation (CRIT)CRIT is a Verizon business application focused on increasing the accuracy, efficiency and speed of the contract rate translation and rate entry processes across ordering ,contract, financial operations, rating and billing systems. Contract Rate implementation is a tedious process where engineers has to manually interact with various legacy systems to implement a contract in 3 hours. CRIT is created from scratch to automate the contract implementation process and achieved the turnaround time of complete implementation to 15 minutes. The whole flow is orchestrated using Aqualogic BPM 5.7 .Integration with various legacy systems are done using Weblogic Integration 9.2 and Aqualogic Service Bus.Responsibilities:System Analysis Requirements gathering and participating in URD (User Requirements Discussion) sessions .Work with an offshore team to design, develop, test, and implement complex business solutions.Coordinate with users to determine requirements. Writing detailed design document for the workflow activitiesProduction support and SWAT/Outage resolution member.Developed complete interface modules to F&E billing mainframe system using MFL,Aspen /Cedar Legacy Rate systems ,Iris Rate management.Developed Rate Translation engine to transform Customer contract rates to legacy rates. Environment: Aqualogic BPM(5.7),Aqualogic Service Bus,Weblogic Integration 9.2,Aqualogic DSP, Weblogic workshop 9.2,XmlBeans,PLSQL, Oracle 9i,Weblogic Server 9.2.

Extended Request Manager (xRM)- Design and Architecture XRM is an ordering application through which CLECs (Competitive Local Exchange Carriers) can place their orders for a product line ranging from simple POTS to DSL service and various value added features. The prime objective of the system is to achieve complete flow through of the requests without manual intervention from request validation to billing completion. The process constitutes validation of the incoming LSR (Local Service Requests), communication with various external systems and legacy applications and order processing systems.Responsibilities:Participation in requirements specification calls with responsibility of signing off Business Requirements Documents (BRD).As a Design Analyst, I prepared POC for Local Validation Engine using JBoss Drools Open source (Business rule management system) to replace ILOG Jrules.I prepared LOE and detailed design document for new business enhancement in the application.Played an active role in setting up xRM application locally using Weblogic integration server to facilitate understanding and testing.Designed and developed new work flows using Weblogic Integration.Code development for business initiatives and Unit testing.Coordinating with the onsite team to enable troubleshooting and support.Environment: Java, Weblogic Integration 8.1, Weblogic Workshop, JBoss Drools, Eclipse, XML, XMLBeans, Oracle 9i, BEA Weblogic 8.1.
