Programming - Developed FPGA IP cores for high-speed serial protocols including: ◦ 10G Ethernet: Developed a recorder, real-time packet inspection, and a 4k/8K video distribution system.◦ Fibre Channel: Implemented a Fibre Channel core on a wide range of platforms (Altera, Xilinx, LabVIEW FPGA). Developed new features and functionality. ◦ RTPS: Wrote a RX module using a new method of managing and assembling out-of-order packets.◦ ARINC-818: Adapted an existing Fibre Channel core to support ARINC-818. Wrote an entirely new streaming conversion core. Prototyped a HDMI to ARINC-818 converter. Project Management and Leadership - Led small teams of firmware engineers to develop test systems for defense applications. - Mentored early career engineers and interns Business Development - Authored customer proposals, developed requirement specifications, and provided estimates/quotes for new business opportunities. - Direct engagement with customers, supported new designs and custom feature additions. - Aided in establishing new line of business via partnership with National Instruments which made existing FPGA IP available in the LabVIEW
