Confidential, IL

Technical Environment: JAVA, J2EE, Spring Framework, WebSphere 7.1, OpenJPA, OSGi, Apache Karaf/ServiceMix, Apache Confidential,, JMS (ActiveMQ), JMX, Bitronics (JTA Transaction Manager), Apache Maven, JavaScript, DOJO, AngularJS, Node.JS, Express, MongoDB/Mongoose, Grunt, Yeoman, JSON, NPM (package.json), Bower, REST

Responsibilities:

• Design and implementation of a modular business component framework allowing large projects to run safely within the same deployment unit using OSGi. Implementation leveraged Equinox and Apache Karaf heavily, as well as Maven. Other tools that were leveraged were, Apache Aries, Apache Blueprint, OpenJPA, Apache Confidential, ActiveMQ.
• Implemented team wide Build/Deploy standard using Apache Maven and Nexus Pro.
• Implementation of an out-of-container Test Harness for an integration-intensive headless application. An inflight application integrating with JDBC, MQ, CTG, WebServices all running within a JTA transaction lacked the ability to execute out of the container. I implemented an end-to-end Test Harness allowing the full J2EE application to be executed from within a JTA Transaction scope and running from within a JUnit test case. This dramatically improved development time and supported regression tests. This Framework more than likely rescued the project. This framework has since became a standard for various development teams. Leveraged tools like Bitronix (JTA Transaction Manager), Spring JUnit Test Framework, Mockito
• Implemented a starter application for the project FEP (Federal Employees Program), using the TestHarness (please see above), Maven, Eclipse, RAD, WebSphere. This resulted in the team saving considerable startup time helped the team successfully implementing the project.
• My final project Confidential was a prototyping effort to identify candidate tools and approaches suitable for implementing large scale call center applications.
• I implemented a prototype using Dojo and an alternate approach using AngluarJS. This is an end to end non throw away POC application.

Senior Software Architect

Technical Environment: Java, J2EE, Apache Axis (WebServices)/SOA Spring Framework, ACEGI Security for Spring, Yale University’s CAS for Single Sign On (SSO), JSP/Servlets, JavaScript, Jakarta Struts, Cascading Style Sheet. (CSS), Hibernate, MySQL, Eclipse/MyEclipse, Apache ANT/Maven, CVS JUNIT/DBUnit, Apache Tomcat

Responsibilities:

• Leading a small agile team of developers designed and constructed a system called Contacts using the current J2EE technologies like Spring Framework (The popular EJB less J2EE Application Server) and J2EE Security system called ACEGI Security for Spring Framework. The system as implied by the name can be used as a backbone for developing other J2EE based systems. It is a template for developing new systems that use J2EE technology. This system used the current agile development process called ADEPT (See Below), ANT and Apache Maven build tools, JSP, Hibernate and Struts. Later another system was developed by replacing Struts with Spring MVC. The other tools used were JUNIT for Unit Testing (Test driven development), CVS for source control management (SCM) and Jude for UML 2.0 based modeling.
• Enabled the middle-tier to be compliant with a Service Oriented Architecture by created a Apache Axis based web services layer.
• Extended the Reference Architectures to use Rich Internet Application by replacing the GUI by using Java and later Open Laszlo.
• Agile Development Process (ADEPT) - Using a small team of agile developers created an Agile development process called ADEPT based on RUP/XP and the teams own experiences on development.
