Summary: RPG (self-learning and OJT) to Java Conversion, Bug Fixing, SQL and some HQL, Hibernate configuration (lots of XML style), Spring (lots of XML style for beans), JavaServer Faces (lots of XML style for beans), XHTML (Web 1.0 UI).




Scope

The project included everything from the backend to the frontend, learning then deciphering RPG, working with multiple team members to gain business requirements knowledge behind the RPG code, backend data and RPG UI screens. Database access and schema related work was primarily done using the SQL Data Explorer plugin for Eclipse. All new work was done inside Eclipse.




UI

I analyzed the RPG UI screens, with lots of help from the RPG Programmers, to determine how to ensure code was converted properly, fixing issues in converted code and in several cases doing total conversions line by line, by hand, from RPG to Java.




Developer and Team Enablement

I offered tips and advice to RPG team members looking to move into the Java world to work on the new project.




Figured out and formally documented how to enable each developer to create a local instance of the popular Quartz scheduling service to prevent possible corruption while accessing the same tables in the server.


Skills Used: Eclipse, Maven, Java, JavaServer Faces, Tomcat, Quartz, XHTML, SQL, HQL, XML, Web 1.0 UI, Spring Framework (no Annotations this project – all XML), Spring Batch, RPG, Subversion (Team), Git (I used locally for my own repos), Windows 7.

Employee (Software Designer V)


Summary: Adding features to the TippingPoint TMC (Threat Management Server) server product. https://tmc.tippingpoint.com/TMC/


• Multiple successful deployments and upgrades to the TMC Web Site and SOAP/REST Services.

• Set up, configured and tested a staging server for http://dvlabs.tippingpoint.com/blog site - code originally written in PHP using Zend; and for the ZeroDayInitiative.com site - code originally written in Python using Django.

• Architected and implemented the TMC migration effort from WebLogic to the new JBoss EAP modular platform.

• Migrated the TMC source base from StarTeam to Subversion then to Subversion on HP TeamForge (based on CollabNet).

• Set up a build server to help HPIT build our product. Used Jenkins and set up the projects to poll the Subversion server and trigger a new build when we checked in a change. The build output was standard Java WAR and EAR format. The build ran custom Ant scripts, one master and several subordinate scripts for localized building within the projects such as service and utility Jars.

• Assisted the architect in clarifying new TippingPoint Entitlements change plans.

• Co-implementer for the new TippingPoint Entitlements change code.

• Conducted HP Cloud (OpenStack) investigation for TippingPoint. In my role at HP I acted at times closer to a DevOps person. I also maintain my own personal servers at Linode.

• Created a UI prototype for the TMC UI Redesign project using jQuery Mobile, JavaScript, HTML5 and CSS3.

• The monitoring tool used by HPIT often failed to let us know when a PROD resource was down. I wrote and debugged a simple Bash script that performed a series of health checks on our servers from outside the HPIT datacenter. This worked so well, the TippingPoint VP told the HPIT people to stand it up in their datacenter and start using it as the formal monitoring solution for our product.
