Amberpoint

Worked with the AmberPoint SOA Management System in various commercial and federal settings including Computer Sciences Corporation (CSC), Defense Information Security Agency (DISA), and MIT Lincoln Labs among others. Worked directly with customers and lead customer teams towards successful deployments and production solutions using system administration skills.

Verisign

Assisted in the development of the SmartPay Call Pricing Module, a real time rating engine for pre-pay and post-pay wireless communications. Project utilized Stateless Session beans, Ant, x-doclet, Hibernate, and JBoss 4.0.x. Focused on multithreaded applications, MBean architecture, and high performance clustering. Responsibilities included core rating engine J2EE development, Java address validation process development, and full deployment shell scripting with JBoss cluster and RedHat Linux kernel configurations. Final QA throughput was in excess of 1000 transactions per second.

The Home Depot

Involved with the development of the new e-commerce website for The Home Depot. Experience included programming in JavaScript, the BroadVision API, SQL, Java, and XML. Also designed and programmed an enterprise wide web image request and conversion system. Website updates were made daily from images stored in DB2 on an IBM 390 mainframe into three sizes to a file system structure designed to optimize seek time. All product images on homedepot.com were created through this process. Used UNIX shell scripting, computer graphics knowledge, ImageMagick, and quality assurance knowledge.

The Weather Channel

Participated in the development and launch of The Weather Channel StarXL, an on-air graphics presentation engine. This presentation engine displays the local forecast for individual cable head-ends (local on the 8s) multiple times per hour. The software was written in C++, utilizing the Silicon Graphics OpenGL and Digital Media APIs. The systems are still on the air today.

Houston Associates/Raytheon

Programmed a real time 3D simulation system for the National Fire Academy in Emmitsburg, MD. The software delivered four simultaneous video streams to training rooms for interactive hazardous materials simulations. The simulation was written with the Silicon Graphics Performer C++ API. Also programmed components that included UNIX TCP/IP and UDP sockets communication and a Windows based User Interface control console written in Visual Basic.

The Cartoon Network

Utilized motion capture hardware and animation software in The Cartoon Network production of the 17 minute pilot episode of The Moxy and Flea Show, a cartoon starring comedian Chris Rock.
