Senior Software Engineer / Java Developer
Northrop Grumman
02.2015 - 10.2016
- Java programming in support of Global Combat Support System / Army. GCSS-Army is an enterprise resource planning (ERP) and logistics application that tracks the varied materials that the Army uses to defend the nation. Everything from bullets to butter.
- My first assignment was to increase performance in the ULLS/AE application that supports the maintenance of Army aviation. The application is written in Visual Basic which was new to me. I picked it up in a matter of a week. I tuned applications to use lazy-loading and tuned the SQL/Server database to use caching. I was able to squeeze 2-10x performance boosts out of the app.
- I created a website to monitor production logging in about a month. The app was based on JBOSS-5, Angular-JS, Bootstrap.js, and JQuery.
- I was assigned to work on SAP/MDS - Mobile Defense and Security. This is a mobile application that tracks Army land-based logistics (including tanks). While the application is written in Java, it is wrapped in SAP’s own development environment which controls the entire SDLC. So much so, that Java is merely a scripting language. There are no Java/EE elements. I solved numerous bugs and created Swing-based automation tools to support the software development lifecycle.
- Linux, JBOSS-5, Java 6, 7, 8, SAP/MaxDB, Angular-JS, Bootstrap.js, JQuery, Visual Basic, SQL Server, MySQL
Contractor, Software Engineer / Java Developer

11.2013 - 02.2015
- Financial Services, Inc hosted the Card Online Servicing system and web site. The minimum turnaround-time for a change to the web site was 6 weeks. Capital One determined to rewrite the system in Java/JEE and host it on their own servers (Weblogic, Tomcat).
- I was contracted to work on the Tetris project using Agile SAFe methodology. My responsibilities involved writing original code to interface the front end UX with the backend Enterprise Service Bus (named Real Time Messaging or RTM).
- As the lead developer of team Prime my responsibilities included leading junior programmers and standing in for the technical lead when needed. I was instrumental in design decisions within the team.
- I was responsible for writing original Java code using JAX-WS and JAXB to call backend SOAP and RESTful web services. I used Spring injection to set up Resources, Components, and Services. I was also responsible for identifying and solving bugs.
- My skills as an algorithmic developer led me to create a "Generic Bean" that uses reflection and introspection to assign values to deeply nested JavaBeans without having to instantiate each intermediate object.
- I have written Ruby and Cucumber to create automated tests based on Selenium.
- I have created front end pages in HTML and CSS using Bootstrap.js and AngularJS.

07.2012 - 10.2013
- After 9/11/2001 it became clear that the reason the good guys couldn’t connect the dots to prevent the bombing was because the data was spread around in data silos. DCGS is an attempt to bridge the gap between these information silos.
- I worked on DOMEX data (Fires/Blueprints and Harmony/HUMINT) that needed to be searchable in the NoSQL Accumulo cloud.
- I wrote algorithms including Document Partition Index, Shingle Index, as well as Z-Order Buffer Geolocation index that were created with Map/Reduce jobs.

- Tech Lead, Architect, Database Separation
- The Federal Reserve, besides its many banking tasks, also manages the food stamp network. Such programs as SNAP require Electronic Benefit Transfers (EBT) in the form of pseudo-credit cards.
- The aging COBOL-based system was overdue for an upgrade. The decision was made to upgrade to a J2EE-based system.
- I was responsible for architecting the solution, retraining the legacy COBOL programmers in Java, leading the Agile development team, and acting as player-coach while I also wrote code. I also acted as an Agile Coach leading scrums and sprint planning sessions.

- The Defense Logistics Agency (DLA) maintains the logistics for all branches of the military.
- The aging ABAP software was overdue for an upgrade. The decision was made to convert over 100 scripts to PL/SQL.
- I and my peers learned ABAP code (an SAP product). While my friends coded their apps by hand, I wrote a compiler to translate ABAP/SAP code to PL/SQL thus reducing the time it took me to convert a module.
- I was also responsible for maintaining several dynamic reports that appeared on the DLA website. These reports were written in Adobe Flex/Flash.
- Technologies: Linux, Java, JSP, Flex, Flash, ABAP, PL/SQL, MySQL, Eclipse, Oracle 11g

- MarineLink was a large database of reconnaissance data that assisted Marines in their tours in Afghanistan. Daily reports of Improvised Explosive Devices, landmarks, and other hazards were recorded in MarineLink to guide Marines through and around hazardous regions.
- I was the technical lead for MarineLink’s web-based front end. The technology had to be fast, component-based, and work on a variety of web browsers.
- I selected Google’s GWT for the server-side Javascript and Sancha’s Ext-JS for the component model. Together they are known as GXT.
- I led two other programmers in a distributed Agile program that involved over 100 people.
- I designed and programmed the user interface, led Agile Scrums, solved technical problems.
