Spent two weeks in Bangalore, India to train sub-contractors and address quality issues.

Wrote detail design requirements and test procedures, developed and tested Object Oriented C++ code for a DO-178B Level A embedded ARINC 661 Graphic Server to be used for multiple aircraft platforms including Boeing’s 787. Developed a library to interface with the proprietary graphics engine hardware. Developed graphical widgets. Lead developer for ARJ-21 project coordinating and prioritizing development for the Graphics Server.

Reviewed and corrected sub-contractor’s design documents for conformance to requirements and effective reuse of existing designs. Interpreted requirements and explained operational concepts for the product. Communicated managerial and technical issues and resolutions between the offshore and on-site teams.

Responsible for integration of In-Flight Entertainment system software functionality; troubleshooting software; worked with management to status integration efforts; wrote and reviewed integration test plans; reviewed code; coached developers with code development and software testing; worked with system test engineers.

Architected major In-Flight Entertainment system/software functionality (including the system database, data load, Flight Attendant GUIs, and a system configuration tool); reviewed system requirements; worked directly with the customer to develop working prototypes; developed software requirements; reviewed top level design documents, detailed design documents; coached developers with code development and software testing; worked with system test engineers; worked onboard aircraft often in foreign countries.

Lead developer for flight attendant entertainment control terminal. Worked with system engineers, program engineers, test engineers, and customers to develop a GUI that has proven to be reliable and user-friendly. Worked on a "tiger team" designing GUI layouts for future product offering that was configurable for multiple customers allowing the company to consolidate software efforts and create less expensive and more reliable software. Spent three weeks offsite with a third party software vendor to design and develop an application with C on a UNIX platform. Added the ability to automatically start predefined digital movie sources when the entertainment system was malfunctioning. Software Development Lead for a C++ application that transfers files over ARCNET and a High Speed RF channel. Created and documented software requirements. As Software Lead for sustaining programs developed GUIs using Visual Basic 6. Worked with system and test engineers to debug system level and software level problems on-board commercial aircraft. Reviewed code/design packages for correctness and effective implementation. Trained new hires. Coordinated high priority tasks critical to product delivery. Identified and worked to remove process bottlenecks. Interfaced with the customer to solve problems and increase customer's confidence. Responsible for the software development and on-time delivery of six international airline customers. Found solutions for some software problems that had persisted in house for over a year.
