PROFESSIONAL EXPERIENCE:

Confidential, Eagan

Senior Developer/Technical Architect

Tools: Java 1.6, J2EE 6, Hibernate 4.x, JPA 2.0, JSF 2.0, JBOSS EAP 6.2,Richfaces,Spring,Spring-Batch 4.0,PrimeFaces 5.0, JQuery, GIT, Soap, Rest, Maven, JBPM 6.2,Angular JS and Jenkins.

Responsibilities:

• Led an 11 member development team.
• Involved in requirement analysis with the customer and onsite team. Created analysis and design models using Rational Software Architect.
• Involved in preparing the Software Architecture Document(SAD) for the application which includes firming up the architectural goals and constraints, design patterns, IOC & dependency injection, error handling, MBeans, XML processing, application servers and Batch processing.
• Developed the framework of the application based on existing Confidential standards. The application had a JSF/Prime Faces/Rich Faces front end, a JSF managed bean as the controller, stateless session beans as an interface to the service layer, Hibernate for backend logic, interceptors for exception handling. Spring AOP for logging exceptions, total transaction times etc…
• Also developed REST web services to interact with the service layer as an alternate to the JSF front end.
• Application used container managed persistence to store data onto database. To avoid frequent querying the application uses
• Designed and developed exception handling framework.
• Designed and coded the batch framework using Spring Batch.
• Designed and coded Message Driven Beans to handle internal as well as the messages that comes from external vendors and end user systems. The MDBs also interacts with the service layer.
• Designed and coded Gateways to interface the various application modules.
• Involved in guiding the team members and also participated in coding the various modules of the project.
• Unit testing and code review.
• Used AJP protocol for load balancing.
• Used tools like find bug, PMD, check style to uncover bugs, format issues etc...
• Used Maven, Sonar and Jenkins to build the source code.
• Used WebLogic as the application server and then migrated to JBoss 6.2 for SQA, test and prod environments.
• Integration testing using JUNIT, regression testing once the application is deployed in the test environment.
• As an onsite coordinator I was responsible for Effort estimation and Project planning activities
• Prepared SOW and proposed solution documents for new RFC developments.
• Maintenance and supporting after the application was cutover in production, support involves weekly builds, deployment on application server (SQA, Test and Prod), bug fixes and RFC enhancements.
• Working as the JBoss administrator in charge of creating application startup and shutdown scripts. Creating and configuring new JVM’s. Configuring the JBOSS environment which includes EJB pool, Thread counts, database configuration, maintaining the entire Java Infrastructure of Confidential LMS systems (1 SQA, 2 test, 8 production and 2 batch servers).
• Scaling JBoss application server nodes in the production environment whenever Confidential cuts over a new customer.
• Generating weekly CPU & memory utilization reports.
• Using profiling tools like MAT, Dynatrace and Jprofiler for performance tuning.
• Analyzing the java heap dump to uncover code issues or configuration issues that is causing performance degrade.
• Creating and scheduling new batch jobs (UNIX scripts and Spring Batch).
• Co-coordinating enhancements and support tickets created by customers with offshore team members.
• Developed and demonstrated POC’s on JBPM (BPMN2.0) and Boniftasoft to provide process management features and tools in a way that both business users and developers like it.
• Using JBPM provided the Business users to configure rules based on changing business needs. For examples a rule can be created restricting the number of Live Animals in a flight or rejecting bookings with dry ice shipments. Through JBPM the application was able to supports adaptive and dynamic processes that require flexibility to model complex, real-life situations that cannot easily be described using a rigid process. We bring control back to the end users by allowing them to control which parts of the process should be executed, to dynamically deviate from the process, etc. Initially this feature was done through drools and later migrated to JBPM .
• Used JBPM to author Decision tables, guided decision table, guided rules and Business processes. Migrated existing Drools DRL files to JBPM.
• Defining the KIE Bases and KIE Sessions via the project explorer in JBoss BRMS application. Build the authored projects into deployable KIE jars.
• Deploying the KIE jar to a maven repository and GIT repository to be consumed by all the application nodes.
• Writing application code to load the jar to a KIE Container, created KIE session to interact with the knowledge base.
• Supply the required data via a Data Transfer Object and executing the appropriate rules. Code changes done to interpret the rules response and presenting it to the end users as a Warning, Alert, Error or Email.
• Migrated the existing LMS USAS mainframe Interface which interacts with the Customs of various countries to use IATA standard approved XML’s using SOAP web services .
• Wrote UNIX scripts to monitor the application and generate ITSM tickets in case of system critical failures.
