I contributed the News::Scan module, which computed statistics for Usenet newsgroups. I took over maintenance of the File::BSDGlob module, which later became part of the Perl core. As a Perl 5 Porter, I have code in the Perl core and standard library.

Key in winning new business for deciBel in AMRDEC’s Software Engineering Directorate and having the company added to an AMCOM EXPRESS Technical Domain team.Successfully delivered as Prinicipal Investigator for SBIR Phase I “Improved Techniques for Optimistic Modeling,” MDA11-031. A $1M Phase II award is anticipated in January 2014.Selected in 2008 as a 10Log10 Technical Fellow, where I was a technical asset to the company at large. Responsible for writing R&D proposals, providing technical review and oversight of proposals, giving talks at 10Log10 Technical Seminars, and leading the teachnical direction of the company. Past talks include Perl regular expressions, intro to git, and pure functional programming with Haskell.Over a period of about 18 months as Integration Lead for JSTM-SuR, I took the team from zero interaction with JLENS SuR to having our software stimulator successfully transmit high-speed radar I&Q and generate detections and tracks. Job one was convincing the El Segundo-based Raytheon team that a bunch of yahoos from Alabama wouldn’t break their radar. Over time and after several trips to L.A., Raytheon came to look for us when they had questions about SuR, second only to their expert software integrator. I wrote in Perl and later C++ a message engine that handles all Command & Status messaging between SuR and JSTM.I was Framework Lead for ORTHON, a system designed to detect roadside bombs using multiple orthogonal sensors. This effort supported the Joint IED Defeat Organization (JIEDDO) and later morphed into the Advanced Fusion Testbed (AFTB). Here I had my first exposure to HXT, the Haskell XML Toolkit, which made generating real and simulated Transducer Markup Language startingly more concise vis-à-vis the Java implementation.

I was a software engineer for AMPS, the Aviation Mission Planning System (AMPS), and the technical lead for my subcontractor on the effort. I supported development of AIM, the Army Integration Module. Think of AIM as Outlook on steroids. AIM allows aviators to communicate with other systems such as Tactical Airspace Integration System (TAIS) and Maneuver Control System (MCS), exchange maps and other intel through PASS and DDS, and even receive live reports from pilots flying active missions. While supporting this effort, I introduced the practices of test-driven development (TDD) and continuous integration to the AMPS team, which had 20+ developers at the time. Developers, management, testers, and QA were all thrilled with the feedback, transparency, and improvement in the quality of the software.For the GMD Fire Control Data Analysis group, I specialized in knocking down technical roadblocks, with examples following. I ported the fire-control subsystem, about 100k lines of Ada, to Linux and GNAT because the team did not have the hardware for running the software natively. I prototyped a system with Perl and Common Lisp for executing large batches of Matlab analyses at the push of a button. I installed and trained the team on the use of Subversion, whereas before there were no formal backups or version-control process in place.My initial hire for this position was with ELMCO, which was purchased by Westar, and later QinetiQ purchased Westar.

Led a team of two developers in design, implementation, and test (written in strict TDD style using C# and VB.NET) of flight-support software to generate and patch runtime parameters of Space Shuttle Main Engine Controller software. We met our 3-month schedule with no known defects.Supported requirements, design, development, and V&V of Advanced Health Monitoring System upgrade.Implemented in C++ a high-speed data acquisition subsystem (using National Instruments hardware) for a data reduction and graphical analysis tool. Designed and implemented in C++ on VxWorks a testcase framework for realtime, hardware-in-the-loop Fault Emulation Unit for the Shuttle main engine controller software. Designed and implemented in Tcl/Tk graphical user interface and command shell for driving the Fault Emulation Unit.I completed an M.S. degree while with Boeing, attending classes on a part-time basis.

I held this position with UAH’s largest research center as a full-time undergraduate and for a few months after completing my degree. During this time, I was an active Perl 5 Porter and also published in The Perl Journal.- Developed in Java a system to query multi-terabyte repository of earth science data.- Developed in Perl a web service for browsing earth science data.- Administered Linux, IRIX, Solaris, Windows, and FreeBSD hosts.

I held this position as a full-time undergraduate.- Administered Solaris and Linux hosts- Developed Perl utilities for various engineering groups

I held this position as a full-time undergraduate. I developed C software for the Advanced X-Ray Astrophysics Facility (AXAF) Offline System (OFLS). Think of AXAF as the Hubble telescope’s x-ray cousin. I developed in Perl an automated system that used Adobe FrameMaker to generate a design appendix for the Software Design Document from the OFLS source code.

I held this position as a full-time undergraduate. I was hired immediately as an incoming freshman as the sysadmin for ASPIRE, the Alabama Supercomputing Program to Inspire Computational Research in Education. While in high school at the Alabama School of Math and Science (ASMS), we were part of the ASPIRE program and were winners of the 1994 national SuperQuest competition. From high school, I already had programming and Linux sysadmin experience. For ASPIRE and the UAH CS department, I administered Solaris, Linux, FreeBSD, and Windows hosts. I was also a lab assistant, so undergraduates and graduates came to me for help with their programming assignments.
