PROFESSIONAL EXPERIENCE

Confidential, Temecula, CA

Java / J2EE Developer

Responsibilities:

• FollowedAgile Software Development Methodology.
• Worked withSoftware Architect, customer and BA to build new requirements and was involved in the process of creation of a FSD and BRD for the entire Stats module.
• Used Pivotal RabbitMQ 3.4.4 as an open source message broker software that implements the Advanced Message Queueing Protocol (AMQP 1.0) for developing the messaging infrastructure of the Amber project.
• Used Apache Cassandra 2.0.12 as an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability and no single point of failure.
• Used CQL (Cassandra Query Language) version 3.0 to create keyspaces and tables, inserting data and executing queries, deleting data, using primary keys, compound primary keys and clustering columns, ordering and filtering query results, composite partition keys and collections.
• Used Oracle Java Version 8 Update 40 and Eclipse IDE for Java EE Developers 4.4.2 to code the classes of the various layers of the Stats module like base classes, data -generation layer and HTTP layer used for making HTTP 1.0 POST requests to external loggers and obtaining HTTP Response codes from them.
• Used Hazelcast 3.3.5 as an in-memory open source data grid based on Java. By having multiple nodes form a cluster, data is evenly distributed among the nodes. This allows for horizontal scaling both in terms of available storage and processing power. Backups are also distributed in a similar fashion to other nodes based on configuration thereby protecting against single node failure.
• Used Chef-Client 12.1 as a powerful automation platform that transforms complex infrastructure into code, bringing the servers and services to life. Whether operating in the cloud, on-premises, or a hybrid, Chef automates how applications are configured, deployed and managed across the network no matter the size.
• Used Spring framework 4.1.5 Dependency Injection where objects define their dependencies, that is, the other objects they work with, only through constructor arguments (or) arguments to a factory method (or) properties of an instance to define the application.xml file for the startup of every module of the Amber project.
• Used Apache Tomcat 8.0.20 as an open-source web server and servlet container to deploy the DLR (or) Mock Logger Application which acts like a mock I3 and Aurora Logger deployed with the same WSDL 2.0, XML 2.0 and XSD 1.1 schema as the actual loggers. The DLR application was deployed purely for testing the Stats module sending log messages to the external loggers.
• Used Google Protocol Buffers 2.5.0 as a way of encoding structured data in an efficient and yet extensible format. The Protocol Buffers were used for almost all internal RPC version 2 protocols, file formats and RabbitMQ messages.
• Used JAXB 2.2.7 marshaller to parse Java objects to SOAP 1.2 formatted XML 2.0 in Stats code so that Java classes are mapped to XML representations.
• Used JavaScript 1.8.5 as a dynamic programming language to set-up the ConfigPoint UI.
• Used MS SQL Server 2014 as a relational database management system while setting up the Aurora system in the lab.
• Used PEI-DB as a database with a custom built CRM and an M&A specific project tracking tool while setting up the Aurora system in the lab.
• Installed MSMQ 6.0 on Windows Server 2008 R2 as a part of the Aurora system installation - this is essentially a messaging protocol that allows applications running on separate servers/processes to communicate in a fail safe manner.
• Used Linux CentOS 7 as a free, enterprise-class community supported computing platform which aims to be functionally compatible with its upstream source RHEL (Red-Hat Enterprise Linux).
• Used Apache Maven 3.2.5 as the build-automation tool to build the Amber project and configure the various dependencies of all its modules.
• Used Atlassian Confluence 5.7.1 as a team collaboration software used to connect the entire project/ business in one place online to collaborate and capture knowledge - create, share, and discuss about documents, ideas, minutes and projects. It can also link to JIRA to automatically link the requirements and retrospectives to the epics, issues and sprints in JIRA.
• Used SmartBear CodeCollaborator version 7 release 7.0 as a peer code review tool that allowed development teams to automate the manual process of code reviews with lightweight code collaboration.
• Used Perforce 2014.2 as a revision control system which managed a central database and a master repository of file versions.
• Used Zephyr for JIRA Server 6.3.15 as a fully featured test management, integrated into JIRA with the same look-n-feel. Testing was integrated into the project cycle, allowing us to track software quality and make empowered go/no-go decisions.
• Used Robot Framework 2.8.7 as a generic open-source test automation framework for acceptance testing and acceptance test-driven development (ATDD).
• Used Ride (robotframework-ride) 1.3 as a lightweight and intuitive editor Robot Framework test data.
• Used JUnit 4.12 as a framework to write unit and integration tests. It is an instance of the XUnit architecture for unit testing frameworks.
• Used Microsoft Windows 7 as the host computer operating system with all its stock applications including Outlook, Word and Excel.
• Used Cisco WebEx Meeting version 7.0 to host and join several team meetings on phone and video to discuss the operations of the project.
• Used Cisco Jabber 10.6 as an instant messaging (IM), voice, video, voice messaging, desktop sharing and conferencing tool.
