Designed, developed, tested and supported new RESTful (JAX-RS) web services using JBoss RESTEasy framework and EJB3, JPA, JMS on JBoss EAP 6 server.➔ General provisioning of Cox Cable customer account and devices using RESTful WS. First, a receiver puts the client input XML messages on the ActiveMQ queue via a router. Then, the processor unmarshals the XML message from the queue and executes a particular workflow. The workflow updates the database with account and device information and sends the device (set-top box) notifications. Lastly, the processor returns the response to the receiver via the router. JMeter was used for load testing.Stabilized, enhanced and maintained batch jobs running as RESTful WS using Quartz scheduler on JBoss EAP 6. ➔ The batch server application comprises of three types of jobs: (1) On Demand, (2) Scheduled and (3) Startup. The functionality of the batch server was enhanced by adding new batch jobs, moving jobs running in other subsystems onto the batch server, and modifying batch job details tables to store additional information.

Designed, implemented, tested, deployed and supported enhancements for the hotel reservation and guest loyalty SDK. Identified, investigated, fixed, and tested defects. Assisted the QA team in integration and user acceptance testing and the application support team in software release and deployment. Worked closely with clients to meet requirements, timelines, budget and SLA. Participated in production outage bridge calls.➔ Developed new services, enhanced existing functionality, fixed defects of an API based SDK used by the consumer website, B2B gateway and call center application. This accessed the IBM mainframe based reservation system, web service enabled guest loyalty system and hotel information stored in an Oracle database. ➔ Analyzed, designed, implemented and wrote test cases for two different methods of guest check-in namely mobile and smart key by modifying the existing create, modify and retrieve reservation transaction and passing the preferred guest check in method and check in details to the backend reservation system.➔ Developed new email and SMS services for hotel guests for their reservation and stay details using CXF (Soap over JMS), Velocity template, ActiveMQ and StrongMail.➔ Led a team of offshore developers to fix defects, assigned priority to the defects, discussed possible solutions, developed testing strategy and deployed the defect.➔ Used Java 6, Spring framework, Hibernate, Maven, EasyMock, TestNG, Drools, Apache Velocity, EHCache, Dozer, Apache CXF, ActiveMQ, ServiceMix, JMeter, WSRR, Caucho Resin, Subversion, Git, Jenkins (Hudson), Oracle 11g, Shell script.

Designed and implemented a new transactional middleware hotel reservation, guest loyalty J2EE system using Weblogic server. Designed and implemented a B2B reservation system.➔ Designed and developed J2EE JMS based asynchronous communication to legacy IBM mainframe guest loyalty system using J2EE, EJB, JMS technologies using Weblogic Server. Weblogic Server administration and configuration of JMS queue/topic, data sources and clusters. ➔ Developed new services to access/modify room inventory and room availability using a http connector and XML request and response to legacy IBM mainframe reservation system using Weblogic Server. ➔ Lead Developer of B2B web service for guest, reservation and hotel detail services using the OTA (Open Travel Alliance) specifications, Axis2 and Tomcat application server. ➔ Maintained systems continuously by fixing tickets and participated in production outage triage calls, troubleshoot and resolved issues.➔ Used Java 5, JDBC, JMS, Ant, Axis2, JUnit, Weblogic Server 8.1, Tomcat, ClearCase, Oracle 11g, Shell script. JBuilder, Altova UModel, XMLSpy, Toad, PL/SQL.
