Systems Engineer for multiple platform products part of the aerospace and defense group.- Developing through to final release systems -F22 radar simulators, phase noise test systems, solar array systems, RF switch array chassis to name a few.- Develop and test engineer as part of the new Raytheon Presidio Automated Testing Line in Agilent. The main responsibility was to make the systems that are part of the Presidio line more streamlined and faster times to market.

- Design engineer for Skyetek (then startup company) HF and UHF RFID reader modules- Designed RF PCB(1 GHz), and power supply modules for the UHF RFID readers- Implemented firmware regression tests for the RF readers (NXP ARM MCUs)- Designed test fixtures hardware, firmware and test GUI's) to accommodate parallel RFID reader testing, RF power VSWR, input dynamic range, FCC regulatory masks etc. The tests developed included multiple readers to be tested at a time fully automated and hence decrease the test times and personnel and time to market from a couple of days to less than an hour.

- RF tests(power, isolation, VSWR, noise figure) of CATV, MATV and IPTV RF devices such as RF routers and set top boxes, channel filters etc- Interaction with design engineers regarding product improvement- Problem solving and debugging new products- Writing procedures and test plan for technicians to stream line and facilitate their duties on a day-to-day basis
