Senior Application Developer

Responsibilities:

• Developed AT& Confidential network fault detection and automation application Rule based Customer Care (RUBY-CC) rule agents which are software modules that simulate domain users on Linux blade platform with JAVA, C++, Perl, Python, XML interfaces with JBOSS, MariaDB/Oracle as back ends. It utilizes commercial off-the-shelf HP TeMIP Expert with embedded ILOG software framework
• Supported RUBY HRO-Billing application which process the contract and order feeds and the data is loaded in ORACLE database. TeMIP events are inserted to the Linux Operation Context (OC) server. The iLog rules running inside the Expert PM, processes the TeMIP events, then read and write the rules-processing results into the ORACLE and MYSQL databases. The daily reports are distributed to external servers using IBM Connect:Direct interface.
• Implemented Common Security Interface (CSI) API Request/Response by using SOAP protocol in XML format.

Senior Software / Automation Developer

• Worked on supporting the Local Number Portability Administration Center (NPAC) which provide the ability to port the continued convergence of wire line, wireless, and IP communications.
• Developed the Agile methodology for the project by using team-based capacity planning and monitor progress throughout the sprint with real-time burn down charts.
• Implemented the Automation Regression, the Sanity Testing as well as the Acceptance Testing suite consists of test cases implemented using (JAVA, Perl, Shell, API Driven HTTP) Scripting and executed each day to ensure the backward compatibility of the system. The results of the regression testing are converted to XML format and reports are generated after loading in the IBM/RQM. Software bugs are kept track by opening appropriate Defects in IBM/RQM tool. The unit testing of the developed software is done using Junit.
• Monitored all the implemented requirements by interfacing with the IBM Rational Collaborative Lifecycle Management (CLM) Tool.
• The RTC (Rational Team Concert) is one of Rational Tool branches used to keep track of the configurations as well as defect management of the project. All the implemented test cases are monitored by using IBM Rational Quality management (RQM) and the requirements for each Epic/Story is referenced by IBM (RRC) branch.
• The NPAC system architecture included CMIP/CMISE Gateway, XML Gateway and GUI Clients. The middle layer (Business Logic Tier) is implemented using JBOSS A-MQ Network of brokers and the Data Access Layer utilizes DAO and Hibernate JPA. The back end DBMS layer is Oracle containing Stored Procedures/SQL Queries. Developed and executed QA End to End Data Driven as well as Keyword/API Driven test scenarios for CMIP/CMISE and XML Gateways after designing them in Test Management (RQM) branch of the Rational Tool with the linkage to System Requirements (Theme, Sub-theme and EPIC) as well as development Stories to be completed in each sprint.
• Developed Automation software for testing of RESTful Web Services developed using spring framework with TCP/IP and HTTP protocols.
• Work closely with other members of the Development and System Engineering teams as well as third party vendor to review the requirements, implement the test plans, and test the effectiveness and quality of software components implemented by the development team during each Sprint.
• During each Sprint continuous Integration is done and each project load is assembled and built (Maven) and installed on the test server (Jenkins) daily after successful acceptance/sanity testing. Once the test server is updated the Automation of integration testing is incorporated using IBM Rational Integration Tester (RIT) by simulating unavailable components of the application. The testing of the front end (GUI) is done by using IBM Rational Functional Tester (RFT) by its Record and Play feature with HTTP/JAVA interface.
