    Worked with the data archive on a variety of projects primarily using Java, XML, C++, Python and Fortran. Worked on the redesign of the distribution system from a VMS based Fortran application into a client-server architecture written in Java on a Unix system. The last two years included responsibilities as the configuration manager for software systems, during a time the software was migrated from a VAX/VMS system onto a UNIX platform. Responsibilities included design of new systems, the maintenance of older software, and the support of the operations group in ensuring that data were made available to the public in a timely fashion.

    Designed, coded, and installed a system to localize transient noises on submarines while working on site at the Johns Hopkins University Applied Physics Lab. This system monitored 288 sensors distributed over the boat, and localized these signals by power and frequency in real time. Signals were displayed on split screen color display with a scrolling graph of the frequency domain above a map of the boat, indicating their location. This project involved coding interfaces to a variety of boards for digitizing and processing the signals, and generating time code signals for synchronization. While this system was only meant as a prototype, the results of the sea tests were so well received that the system was implemented for noise tests on boats released from maintenance for mechanical repairs.
