Developed requirements and C code to add a 10gigabit ethernet networking interface to existing DPAA Driver software for a PPC T2080. Updated MDIO software for accessing clause 45 registers in addition to clause 22 registers.Performed embedded system development for Honeywell in C++ on VPX chassis boards utilizing VxWorks RTOS running on a PPC processor. Wrote an I/O interface library to interface with kernel modules and drivers. All work used FACE conformant interface and communication layers to transmit avionic navigational GPS and IMU data over RS-422.Technical lead for a team of 4 working with Bell Helicopters in their V280 Flight Controls Division.Created Test Cases and Procedures for high level requirements coverage with a focus on also receiving low level coverage.Created scripts for improving day-to-day functions.Ran test procedures on target hardware triplex FCC's via a test bench.Trained engineers for on-boarding other EXB staff into Bell's standards and procedures as well as acting as a liaison between Bell's Flight controls leads and project management.In a separate engagement with Bell - Performed an in-depth DO-178B SOI2 compliance review for Bell Helicopter’s V280 Flight Control’s systems, software, requirements, architecture, and artifacts.Presented and delivered findings to the V280's Project Manager, Head of Engineering, and Test Lead.Developed an end user Android application for communicating with a mock-up implanted Bluetooth medical device for future use of interns/bench time, along with full Systems/Software requirements and user stories to assist with development.

Designed DO-178B compliant software level tests for LM-100J’s Color Multipurpose Display Unit embedded ADA code in VectorCAST.Designed DO-178B compliant low level requirements for Lockheed Martin’s LM-100J project in DOORS.Created standards for unit testing stubbed out functions against low level requirements while also attaining MCDC coverage, range testing, robustness testing, and completeness for future static code analysis as well as data and control coupling analysis.Personally created an application in C# which could take Boolean logic in the form of a statement and generate an exact set of test cases which would provide full MCDC coverage of that statement.This was done by transforming the statement into Reverse Polish Notation, generating a truth table from the logic received, and applying a personally created algorithm to gather correct test cases.
