PROFESSIONAL EXPERIENCE:

Sr. Developer

Confidential, St. Petersburg, FL

Responsibilities:

• Developed batch based application using spring/core and Java 7 to import large volume of segment data.
• Designed & developing Apache Camel based integration solution to develop a proxy application to receive, translate & route requests to back end systems. This is based on EIP patterns & takes care of SOAP over JMS to SOAP, SOAP to SOAP & REST to REST routing. The framework is based on spring and takes care of logging, invoking translators for request/response processing and routing.
• Developing major enhancements to DROOLS based campaign engine that computes loyalty rewards based on business rules. Also developed SOAP based many web services. Used Junit for testing. Used Hibernate/JPA 2.0, PostgreSQL, EJB3, Java 7, Drools & JBoss 8.

Lead developer, lead

Responsibilities:

• This involved design, development and implementation of an “integration solution” to integrate different s/w products from the company. Technologies used: Spring Integration (2.3) & Spring Core (3.2.3). The solution currently supports integration using SOAP based web services and capable of integrating using REST, JMS/AMQP based messaging and file based exchanges.
• Introduced RESTful services using Spring & Soap based services using JAX-WS Spring-Web Services; Currently heading effort to introduce a large suite of RESTful services.
• This involves services design, lead developers in the development of a portfolio of services using SOAP & RESTful services & hands on coding of many services. The project included standardization of SOAP messages. RESTful services included hyper media driven(HATEOAS) REST services. The technology used were Spring MVC (3.2.3), Spring Web Services, Spring (3.2.3), Spring HATEOAS, JAXB, JSON & XML
• Designed, hands on coded and implemented of Spring POJO based JMS processing & POC on AMQP (Rabbit MQ)
• Designed, developed & implemented Spring POJO based JMS solution to process events. These were capable of processing JMS messages containing objects. Also conducted a POC to process JSON messages using AMQP (Rabbit MQ). Technology used is Spring (JMS) and Spring/AMQP.
• Designed and implemented of workflow within the application & designed many new modules
• Currently leading an effort to design, develop and implement a homegrown work flow system that helps users to define work flows involving screens and process work flow instances. Technologies used are: Spring (core) & Hibernate 3.1.
• UI Layer usability improvements
• Introduced the concept of work spaces containing widgets using which users can carry out most of tasks in a single screen (with least amount of mouse clicks).
• Introduction of mobile technology using HTML5 and JQuery
• Introduced mobile screens accessing back end data through RESTful services.
• Enhancements to batch framework
• Enhanced “End of Day” framework which uses multi threading heavily based on the producer-consumer pattern.
• Performance improvement initiatives
• Increased through-put of batch jobs and reduced response time for selected online transactions. Introduced performance environments to evaluate performance of on-line transactions. Used JMeter, JProfiler. Worked on many SQL & index fine tuning as part of this initiative.
• Introduction of Continuous Delivery Pipeline
• This involved automation of build, deployment of installer and moving it through stages of testing to achieve continuous delivery of the product
• Periodic technology upgrades

Technology used: JEE 6, Java 1.6, Hibernate 3.1 ( around 200 entities), Spring Framework 3.2, Spring Integration 2.3, design patterns, maven/gradle and JMS1.1, JDBC, JProfiler, Weblogic 11g & SQL Server 2012 ( including SSIS & SSRS - SQL Server Reporting Services) .
