Architect

Responsibilities:

• Design and architect a scalable spring based web project using maven.
• Set up and conduct technical meetings to discuss about design approach for requirements, development strategies and security issues.
• Create architecture diagram, context diagram and have them approved by enterprise team. Prepare technical documentation about the design/development work that will be used as reference for implementation phase
• Present the application design model to business team for feedback and approval.
• Create and configure data project to use spring repository approach. Design involved using Hibernate implementation of JPA specification. Create entities with necessary relationship for the database tables applicable
• Create and configure service project that can will have classes implementing business logic. This layer acts as a bridge between controller project and data project. Used spring auto wiring and dependency injection to configure the beans over xml based approach.
• Create and configure controller classes to map user request to appropriate methods. Used Jackson mapper to convert data to JSON format
• Develop JSP pages with JQuery to present rich UI to user. Most of data were loaded using Ajax technology. Used datatables.js for creating table. Created css file for design layout of the web application
• Interacted with Enterprise Single Sign on ESSO team to integrate the application for authentication.
• Worked with RAM team to create roles for authorization and implemented code related to the functionality
• Designed and implemented JUnit test cases to performed unit testing. Used mockito library to create mock object
• Configure Jenkins to have continuous integration set up for development stream of clear case.
• Collaborated with configuration management team to invoke build and deploy scripts for performing the same to UNIX server using iCART
• Worked with infrastructure and fulfillment team to create application servers for various environments along with installing required certificates
• Engaged with middle ware team to create apache load balancing server

• Involved with upgrading existing Java 6 based code to Java 7 version

Environment:

JDK 1.6/1.7, Tomcat 2.6/2.7 , Spring 3.2, JPA 4.2, JSP, MS SQL Server 2008, Log4j, maven, Windows xp, JQuery/JavaScript, CSS, XML, Clear case, JUnit.

Responsibilities:

• Set up the spring batch application using maven.
• Collaborated with other developers in the design for the project
• Developed the entire publisher module. Command center listener will listen to the messages published by this module. These published messages will invoke various type of job like delta cycle, trade cycle etc.
• Autosys scheduler and automation tool is used to monitor the job and handle run window. Email messages will be generated if any failure or warning scenarios occur. Autosys job can also be run to publish adhoc messages.
• Implemented functional testing called Randomizer to mimic production scenario. Scenario involved publishing random messages of various types and necessary records inserted into database at random intervals with varying count. The code also tests the output after the database records are processed by command center for success and failure conditions.
• Windows scheduler is used to invoke the randomizer. Entire process of command center tested using this rigorous approach from development perspective for stability and defect free code.
• Move the configuration files outside the jar so that job configuration can be changed without need to have code change followed by entire release migration process.
• Used AOP to log input parameters as well as output results for spring job methods.
• Created an enhanced version of rolling file appender used by log4j. Enhanced version will have file named with timestamp details that will help during debugging. Also original version creates all log files with same creation date. Hence there was an issue during archival process. The enhanced version addressed the issue.
• Worked on the build and deploy scripts that can be invoked by iCART tool.
• Configured Jenkins for running JUnit test cases as well as perform build and deploy.
• Implemented jar signing process with maven. Used maven based encryption to have the password encrypted.
• Performed build and deploy to various development environments using iCART. Created release iteration and release notes for builds that would be promoted to higher environments.
• Mentored junior developers during implementation phase of the project providing guidance and use of various design patterns.
• Collaborated with Factory Engineering team to have the jars uploaded to nexus repository
• Analyzed the issue related to database connectivity with SQL Server 2008. Identified issue was due to difference between 32 bit/64 bit server and associated dll file. Provided solution by adding the right version files in class path.
