I have an extensive and varied software and systems engineering background spanning more than 35 years. I have developed systems for NASA, various DoD entities as well as in the commercial aerospace arena. I enjoy challenges of transforming and combining technologies to create systems that answer a need.

From May 1999 to May 2001 (2 years 1 month) Senior Software Engineer @ Led team developing simulation of conceptual Electronic Warfare systems intended for us on the Joint Strike Fighter (F-35). Assessed existing software for possible reuse, specification of virtual operating system services, hardware specification and integration. Models included Radar Warning Receiver, Radio Frequency Countermeasures and Infra-red Countermeasures. Models developed using the Ada95 targeted to Windows NT, Irix and VxWorks running on Motorola PowerPC SBCs. From May 1997 to April 1999 (2 years) Senior Software Engineer @ Joined a small start-up company developing network switching devices. Developed the real-time knowledge base, trained software engineers in the use of Ada95, optimized software for efficiency, and contributed to the development of in-house Real-Time Operating System (RTOS) for the Argonaut RISC core processor. Development in Ada95 using the GNAT compiler on Linux, Windows NT and Solaris host systems. From August 1998 to October 1998 (3 months) Senior Software Engineer @ Developed a Unit Training Device for the A-10 ground attack aircraft. Responsible for models of the flight dynamics and flight control, simulation of aircraft systems, environmental effects and the electronic combat environment and aircraft electronic combat systems. Developed and hosted on SGI Irix operating system with REACT real-time extensions. Development language was primarily C.
