October 2009-Sept 2011

Java Software Engineer

I helped develop a working baseline development platform for the U.S. Coast Guard Finance Center’s Core Accounting Suite(CAS) of J2EE financial applications from the legacy delivered source code. This involved making ANT builds, parsing tools, and file compares. Next I made several improvements to the applications involving vendor management, purchase requests, accounts payable, and warrants. Some of the tasks involved developing new SOAP web service endpoints and implementations to improve the performance of daily tasks involving accounts payable and vendor management and improving the performance in the multi-threadeaded, concurrent, real-time environment. I designed the solutions, implemented them, and wrote both JUnit and UAT test plans for the solutions. Plus, after deployment, analyzed UAT test results. Lastly, we created a suite of JUnit test cases for the delivered and production code to aid in future development. CAS is a suite of financial applications used by units in the field for procurement, purchasing, accounting, user management and other tasks. It is a made up of several 3-tier J2EE applications. They involve JSPs and AJAX on the front end calling the Webservices and SessionBeans in the middle, and Oracle 10g on the back end.

Software Engineer

I am developing a J2ME application for grocery store shoppers. This application will manage the users shopping list and search online weekly grocery store circulars to find which store nearby has the best savings that week for the shopper. It will also allow the shopper to see a particular item a particular store is on sale at any other stores. I'm developing this as an MIDlet using the high-level J2ME apis, internal J2ME RecordStore for data storage, and HttpConnection to search online circulars.

I developed a Java peer –to-peer application that could be used on the Google Android G-phone platform to manage a cities emergency response/rescue plan. This application is integrated with pda functions, Google Maps, and the SQLite database to keep track of victims needing rescue, ambulances, food/water, and medical supplies. I designed a database schema run on the SQLite database that included in the Android platform. This allows emergency workers to have updated amounts and locations of emergency medical supplies, food and water supplies displayed on the Google Maps application. Updates to the database tables would be sent to all the other devices using wireless messaging which are functions of the Android platform.

Now working on a grocery store circular deal locator for Blackberry, Palm, and other J2ME devices.

Auburn Hills, MI

September 2006-September 2007

Software Engineer

Developing server-side applications to enhance and improve performance of Chrysler's EBMX supplier file trading/file transfer platform, as well as admin tools to aid in the diagnosis of problems. EBMX is a J2EE application based on the I-planet ECXpert Rules Engine. The interface we implemented for the ECXpert Rules Engine was an MVC-Struts 1.2 based front end where each supplier could login and view the part specifications for the vehicles that they are interested in getting their parts sold on. I had to write Struts actions, Java Sevlets, JSPs, Javabeans, and Perl & Unix scripts that would be involved in the parsing legacy EDI files, monitoring for excessive activity,and notifications of non-conforming files being uploaded. I was also involved in requirements gathering, design, implementation, and testing. The application was deployed on Websphere Application Server 6.0 & Sun I-planet. Wrote and edited SQL queries and stored procedures for DB2.

OnStar Unix Level 2 support

I provided support for J2EE applications deployed on Solaris platforms that make up the OnStar service. I performed application change deployments and had 24x7 on-call duties for 11 J2EE applications. I wrote and maintained Unix scripts that were used for controlled starts, stops, and file changes. I wrote test scripts for new deployments and deployed new OnStar applications on new servers. On a 24x7 on-call basis, I performed emergency restarts root cause analysis. I also helped implement a new interface for level 1 OnStar advisors to help them deal with client issues. This was a J2EE servlet based application providing them an interface to the same OnStar databases, routing direction files, and OnStar personal calling account information. This application parsed Onstar Handsfree Calling orders using a IVR/VXML format. I also wrote SQL stored procedures and new VXML grammars.

Project: Delphi Automotive Supply Chain application

July 2004-December 2004

I implemented some front end Servlets and made changes to EJB SessionBean logic that communicated with an IBM WebSphere ICS(InterChange Server, J2EE connector platform) application used by Delphi Automotive. It used WebSphere ICS interfaces to communicate with the existing business logic and the DB2 database using JDBC. This provided an interface for part defect reporting and tracking. I received class and process design diagrams from Rational Rose UML diagrams to be implemented into SessionBean logic or object changes. The goal of my Session Bean logic was to eliminate redundant error reports. The front end for entering this was implemented with Struts with Actions used for different error reports. I wrote unit tests using Junit for my new actions
