Software Test design; Perform data analysis to establish baselines for evaluating tests (PC++, C#, WPF, Signal Processing).

Hands-free voice recognition and control (C++, C#, WPF).

Transported UNIX utility for comparing sets of requirements toWindows 7 using Win 7 C++ SDK and Visual Studio. Validation of specializedAPI capability. Transport of a number of utility Windows XP applications to Windows 7 (C++, C#, WPF).

Evaluation of transition of demo and utility software to Windows 8 (C Evaluate impact of changes to OEM software.Evaluate use of C# and .Net. Medical device design and interfacing.

Built Java SE simulation of four, six, and eight medical device communication port to estimate bandwidth requirements for a commercial communication hub to perform expected data collection and communication tasks. Employ multi-treading on multi-core process to achieve operational requirements.

Performed Monte-Carlo evaluation of proposed design for communication hub (C++, Java SE, C#, WPF).

Experiments with Python were performed to see if it could achieve the required throughput. While it provided the desired flexibility and compatibility to our C++ system, its application was limited. (C++, Python)

Evaluate transition to C# using .Net support. The program portion was done using Agile as an experiment to evaluate its usefulness. Developed ASP.Net demonstration for management’s consideration. (C#, MFC, .Net)

Doors was frequently used on a number of Northrop projects. However it was occasionally mandated by the customer contracts. Requisite Pro was also mandated on a number of projects. However, we never used it on internal Northrop projects.

Evaluation of advantages of embedded GPS over external GPS operation.

Litton, Woodland Hills, CA Software Engineer Nov1987-Dec 2000

Serve on software engineering development teams as well as systems engineering test teams. Perform maintenance and repair operations on support equipment and test equipment. Perform analysis and testing of both external and embedded GPS systems.

Support existing PDP (FORTRAN) based airborne vehicle simulator (MatLab, UML). Perform data analysis to establish expected results. (UNIX, Vi)
