Contractor to government client, to work with them in developing a spatial model to help forecast MidAtlantic Sea Scallop growth. The model is based on the Miller-Notingham Growth Model and includes work by Dr. Debora Hart. It also includes a Universal Kriging algorithm based on the book by Noal Cressie to interpolate dredge survey data to align with grid data that defines the Mid-Atlantic and Georges-Bank fisheries.Several programming languages are used to parse raw data, model growth, control and manage simulation, and plot results.• Fortran• Python• MATLAB/Octave

Developing embedded firmware for Test & Training Instrumentation.Flexible and secure military test range systems are necessary to integrate new aircraft and weapons technology into a complex training scenarios that can include aircraft of different nations and generations.Rockwell Collins test and training instrumentation solutions meet critical Department of Defense (DoD) requirements to provide time, space, position information (TSPI) and additional platform test data while employing a more robust, spectrally efficient data link, including multiple independent levels of security (MILS). This keeps vital data flowing securely between aircraft and ground battle space components. Our technology gives you common test and training infrastructures for improved operational realism.

Senior Systems EngineerTechnical responsibility for all software development and design in support of media scanners and card readers. Managerial responsibilities for team development and hiring.• Defined software configuration management process.• Defined software release management process.• Moved image formation from host API into embedded scanner firmware resulting in a greater consistency, repeatability of resulting image.• Software languages include: C/C++/C# and assembler.• Software environments include Linux, Windows, GNU, and Visual Studio, Analog Device VDSP++.

Working with team to develop processes that make sense rather than to satisfy a check mark on a process list. Involved in all areas of software development; requirements gathering/ analysis/ management, code development/ inspection/ standards/ configuration management, and test & integration documentation. Various roles of increasing responsibility in the design and development of application and test software. Including but not limited to (no particular order)Software Engineer, Senior StaffSupport systems engineering in rapid turn around of software applications using Matlab. Develop quick studies to verify proper operation of FPGA designs, i.e. test bit vectors. Software developed using today’s languages; C/C++/C#.• Improved both development time by 50% and accuracy by 100% of FPGA designs by making bit compatible test vectors via Matlab. The application was to model the front end of a digital receiver. Output was variable width fixed point or floating point.• Streamlined device testing from 1 week to 5 hours by utilizing Visual Basic Applications in Excel to automate test procedures. Design includes automated control of lab test equipment, i.e. spectrum analyzer, DMM, and signal generators. Interface was part of a Windows GUI based system written in C# via Visual Studio.Cryptology Software EngineerImplement government crypto-logic algorithms on application specific platform (Advanced Infosec Machine) using custom real-time embedded assembler.• Use of design specific language, Cryptol, thus cutting debug time in half.• Applied Object Oriented Design techniques to assembler software design.• Implemented new algorithm ahead of schedule and below budget with full documentation.DSP Software EngineerWorked in the DSP Group developing digital signal processing algorithms for vocoding and echo cancellation.
