L-3 Communications Display Systems – F-35 Joint Strike Fighter cockpit display: Participating in software development, software requirements, software integration, and software verification activities. Software development in Green Hills Software INTEGRITY, using C on a PowerPC architecture. Requirements management and traceability using Telelogic DOORS. Microsoft Visual C++ to develop Fibre Channel software integration tools. Verification activities focusing on certification of system services software and embedded OpenGL software libraries and drivers, including utilization of LynuxWorks’ LynxOS. Also helped author DO-178B documentation in support of the NASA T-38 avionics upgrade.
Siemens Airfield Solutions – Developing next-generation graphical user interface for runway and taxiway lighting system control and monitoring. Using Visual Studio 2005/Visual C++ and MFC to create flexible graphical views of equipment status, integrated with the control system, to provide near real-time access from anywhere on the airfield network.
L-3 Communications Avionics Systems – Key team member developing the aircraft navigation features for the SmartDeck integrated flight display and control system. Focus on RTCA/DO-229c WAAS GPS navigation. Developing in C++, according to FAA’s OOTiA principles, using Green Hills Software’s MULTI development environment and INTEGRITY real-time operating system on a multi-processor MPC8245 hardware platform. RTCA/DO-178B level B software requirements capture using DOORS and UML. Simulation and development test tools written in Microsoft Visual C++ on Windows.
Ryan International Corporation (now AVIDYNE) – Member of a small team developing a real-time embedded avionics hazard display. Performed digital hardware and FPGA troubleshooting, software system design, implementation, testing, and helped drive a Level D FAA certification, using practices based on the Department of Energy systems development methodology, modified to suit RTCA/DO-178B requirements. Implemented in C on a PowerPC platform using Green Hills Software’s INTEGRITY real-time operating system. Main software development efforts included RTOS board-level software, drivers, and sensor interfaces, but also contributed to OpenGL application software. Performed initial work on RTCA/DO-200A aeronautical database development.
BFGoodrich Avionics Systems, Inc. – Real-time aircraft cockpit Terrain Awareness & Warning System, implemented in C in accordance with an ISO-9000 certified software development methodology. Implemented on PowerPC 8240 using MQX RTOS. Helped define system requirements and user interfaces, implemented key software components, and participated in FAA required DO-178B level C certification. Wrote mock-up display software in Visual C++ on Windows NT and participated as team member writing simulator to drive FAA-required Human/Computer Interface evaluations. Simulator software included a Windows device driver to interface with realistic flight simulator hardware. Also wrote distributed test application components that communicated via sockets, UDP, and RS-232, simulating avionics sensor inputs.
ADB-Alnaco – Team member for two years creating a state-of-the-art, distributed, fault-tolerant client/server control system for runway and taxiway airfield lighting at the Gardermoen airport in Oslo Norway. Used Visual C++ on Windows NT to create applications and DLLs to provide a graphical rendering of the airfield, to be used by maintenance workers and air traffic controllers to control, monitor, and diagnose the system. Also wrote multithreaded socket and SNMP-based network components to interface with intelligent control panels used by air and ground traffic controllers.
Stillwater Computing Services – Wrote software for a PCMCIA cryptographic flash memory storage device, including a Windows application, a C++ library implementing the PKCS #11 (Cryptoki) programming interface, and firmware interfaces and C++ classes which wrapped them. Bob Evans Restaurants – Consulted on Windows NT application architecture and ported OS/2 applications to Windows NT. Converted dial-up credit authorization application to TCP/IP.
