Arlington, Va, Us

I worked on Programs (F-22 Radar (Embedded C++), Thermal Weapon Sight (TWS) (bit-wise embedded C)) before settling into the bulk of my career at Raytheon in the central tools and processes group, responsible for all Software Engineers in N. Texas. Our purpose was to develop tools and processes to maximize efficiency using six-sigma (I'm a six-sigma Specialist) as well as helping us to achieve the CMMI SEI Level 5 ranking (the highest level there is) during my time there. I developed various web tools to help compute, store, and report on metrics for all the Programs in N. Texas.as well as developing tools for our customized source control module (base tool was Telelogic's Synergy, but we heavily customized it). I also worked on a website with custom reports using Peregrine Asset Center as a back-end. This was used to track our hardware and software assets.
