Embedded Software Engineer IV for a large aerospace company. Principal assignments in R&D and rapid development projects.

• Ada Simulator Validation program: first redevelopment of a flight simulator in the Ada programming language. I worked on the I/O and executive and getting two computers to talk to one another over an HSD bus link, and then stayed on to do the wind profiles, part of the flight software, and general on-site integration and debugging. (1986)
• Modular Simulator programs: on the internal R&D program I got segments of a real-time simulation running on different computers tied together by Ethernet to function as one simulation, and I developed an embedded training component using a real time inference engine. I helped Wind River Systems port Verdix Ada to VxWorks. On the contract R&D program for the Air Force, I developed the executive, I/O, and Bus Interface Unit, which tied the parts of the simulation together over an FDDI network. (1987-89)
• The structural model I developed for the Mod Sim program was combined with work Gary Kamsickas did on systems engineering a generic air vehicle training system to form the Domain Architecture for Reuse in Training Systems (DARTS). We used DARTS as the basis of the demonstration of process-driven reuse and domain engineering we did with the Software Productivity Consortium for the STARS program, for which our team received an "Outstanding" Quality Pride award. (1990-1992) Other groups within the company have used DARTS for their projects, including the Lunar Rover and Space Station Payload Rack simulations.
• Avenger trainer for DIS: wrote executive, cockpit interface, missile dynamics, and audio software for an Avenger trainer which was the first simulation from an aerospace company certified to operate in the DIS network. I turned DARTS into a virtual network architecture, VNET, for this system. Following this, I helped people on the International Space Station program adapt DARTS+VNET for their rack system architecture. (1992-1994)
• Developed software for the Advanced Computing Group to convert models from Boeing CAD to Open Inventor and animated these models to illustrate a proposal. Received an "Outstanding" Quality Pride award. This work led to my interest in 3D modeling and Virtual Reality Modeling Language (VRML) which led my being able to serve as a company-wide resource in 3D modeling and animation. (1994-1998)
• Around this time our group joined the Phantom Works organization, though we were frequently loaned out as resources to other groups. I developed the website and email list and archive software for the group, wrote readiness test and recovery software for MIR Pathfinder program, worked on system architecture and hardware interface for the E-FOGM program, and contributed to the 1553 bus software on the International Space Station. (1999-2000)
• Designed and implemented vehicle dynamics software for Ground-based Missile Defense program. (2001)
• Designed and implemented a web-based configuration management and groupware system using PHP and MySQL for GMD and Theater Sim R&D program. (2001-2002)
• Member of the system architecture team for the Future Combat Systems Lead System Integrator. (2003)
• Designed and implemented XML tools for the Network Centric Operations thrust in XSLT and C++ using Xerces, Xalan, and MSXML that allowed their scenario modeling tool to import HLA federations. Received Bronze Phantom Award. (2003)
• Wrote Southern Cross data analysis and visualization tool using C++ and the QT API to enable post-mission analysis of larger HLA simulations. (2003)
• Boeing Rocketdyne organization Space Shuttle main engine Advanced Health Monitoring System. Developed C++ coding guide for Phase III. Developed Real Time Vibration Monitoring System simulator using TI Code Composer on a custom 5-CPU TMS320C40 DSP board. (2004-2005). Left when NASA de-funded the program.

Principal Engineer, Systems Design Engineer, Senior Systems Design Engineer for a flight simulation company.

• Panel trainers for Boeing 727 Rudder, Elevator and Stab trim; Electrical System, Hydraulics. Detailed design, simulation and display software in MC6809 Asssembler, integration and test.
• Hydraulics, Landing Gear and Secondary Flight Controls for B-747 and B-757 Ground Maintenance Simulators for British Airways. Developed design, acceptance test procedure, system simulation software in FORTRAN 77+, integration and test.
• Electrical system for RC-135-W Operational Flight Trainer for SAC. Developed design, acceptance test procedure, lead electrical design, system simulation software in Fortran 77+, integration and test.
• Hydraulics, Landing and Gear, and Secondary Flight Controls for Saab SF-340. Developed high level Instructor Station language and compiler into SEL/Gould Assembly language. Project engineer for U.S. phase

Youth Director, Branch Executive. Responsible for operations of YMCAs: budget, program, facilities, staff supervision and training, considerable work with volunteers, fund raising, youth counseling.

Management trainee, stockroom.
