Software Engineer 9/2005 to 10/2009

Worked as a Sr. Java Developer and Database Specialist during this time. Was employed by several firms to include Tek Systems, Robert Half, Viper and Surrex Solutions. A sampling of clients and duties are listed below.

Client: L3 Coleman Aerospace (10-09 to 11-09)

Assignment: Developer/DBA

●Migrated databases from Sybase to Oracle 10G converting the DDL to Oracle DDL and import control files. Migrated data using Sybase BCP and Oracle’s SQL*Loader utility. Converted T-SQL triggers to Oracle’s PL/SQL triggers and sequences for primary key generation.

●Converted complex T-SQL multi-query report to a PL/SQL package that returned data using reference cursors.

●Modified Perl script to call packaged procedure for data and accept as reference cursors.

●Environment: Oracle (10G RDBMS, Enterprise Manager, RMAN, PL/SQL, SQL*Loader, SQL*Plus,), DB Artisan, Sybase BCP, Perl, Windows XP, Sun Solaris.

Client: American Automobile Association (9/07- 5/09)

Assignment: Java Developer

Worked on several internal projects which are listed. Technical Environment: Eclipse, Java (JDBC, JAXB), JUnit, TestNG, XML/XSD, AJAX, Javascript, CORBA, SQL Server 2000, Visual Source Safe, XHTML, HTML, JBOSS, SEAM, JSF, MySQL, NET Acuity IP address database, Web Objects, FireFox’s FireBug and User Agent Switcher.

●Travel Agent Portal: Inherited offshore code to maintain for the System Administration portal. Added AJAX calls to query database for custom delete messages. Created common Javascript methods to dispatch the display of the appropriate message. Replaced java code that generates JSF components to JSF components, HTML and CSS in XHTML to comply with MVC architecture. Initiated effort to normalize database.

●Transaction Repository: Development of a repository of travel booking information. Development effort included the use of XMLStream to store XML representation of java objects in SQL Server. Free Marker was utilized for the generation of export files. Developed JUnit test cases to mimic travel bookings. Developed TestNG travel booking tests for bookings made using web services.

●Zip Code Server: Development included the creation of Java classes to access NetsAcuity’s IP database. The SQL Server database that contains club information was updated to included geographic locations that are to use or be excluded from using the enhancement. Modifications were made to the CORBA’s IDL for access to the database classes for IP addresses location. An enhancement was put into place a month after production deployment to include or exclude counties from using the IP Interrogation feature. Another enhancement was added to exclude IP addresses that were deemed to be using mobile connections to the internet. This application calls the zip code server with the IP address provided with the HTTP header. If the geographic location of the IP address is included in IP interrogation an HTML page is returned to the client with a Javascript reroute to the club that serves that area. If the IP address is excluded from IP interrogation a Zip Code data entry page is returned to the client. Developed multithreaded java program to query the NetAcuity database directly using randomly generated IP addresses to “stress” test the database. Expanded on the program to send HTTP requests to the Zip Code application using the random IP addresses to stress test the entire application. Populated a local MySQL database with a free download of over 7 million ip address blocks and their geographic locations. Developer query to retrieve ip address blocks by city and state to provide test data to use when including / excluding IP Interrogation.

●Search Engine Marketing Trends: Enhanced www.aaa.com placing web trends tags for search engine paid placement tracking. Development involved the creation of a Javascript API that is included in the Web Object components that comprise the user interface. A Web Object subproject was created to facilitate the creation java script to include the API and use it.

●Zip Code Application Rewrite: Rewrote the application interacts with the Zip Code server eliminating Web Objects and replacing with JSF and SEAM. Incorporated the Search Engine Marketing Trends project and IP Interrogation projects. Replaced applications initialization files (name value pair) to application XML files. Developed common classes to digest application XML files.

●ATI Web Services Enhancement: Upgraded web services for requests to American Travel Incorporation so that registered AAA travel agents using Travel Connect receive credit for hotel bookings. Development involved alerting the client web service Java classed to use registered travel agents for identification. CORBA IDL was altered to include the agent’s credentials as it is passed from the application to the server acting as the web service client. The Travel Connect administration application was upgraded to maintain ATI travel agents.

●Partner Hotel Boxes- aaa.com hotel search result advertisements. Implemented enhancement to hotel search results to display AAA partner advertisements in hotel search results page. Development involved updating database classes JDBC code to retrieve business partner information. CORBA was modified to contain this new information as it is passed from the “travel server” to the application. The user interface was modified to display the partner’s ad in the hotel search result list.
