Creative solutions to demanding Electrical Engineering problems with designs that are exciting by nature.Throughout my career it has been my passion to continue to learn new concepts and pass them along to others. My proven track record has expanded into various fields that include areas in: computers, internet protocols, packet transmission, microwave transmission, radio / TV broadcast engineering, submarine detection, locomotive traction systems, railroad signaling crossing protection, telecommunications test methods, radio astronomy, satellites, antennas, electronically controlled pyrotechnics, microcontrollers, and veterinary instrumentation. A creative thinker, I have been instrumental in designing, using my analytical skills on projects for product improvement

Tested and analyzed: Metering Subassembly using Final Test Fixture, JMP Statistical package Results: broke supplier looping of product for rework, tightened specs and testing procedure Developed: Digital Radiography controller using OrCAD and PADS software based on PIC chip Results: project dropped during development due to lack of design specs and other prioritiesDeveloped: VT950D KeyPad Interface Board using OrCAD and PADS software Results: kept product manufacturability from going obsoleteDeveloped: LaserCyte Cooler as core team lead in collaboration with outsourced firm Results: allowed LaserCyte instrument to keep working in adverse temperaturesManaged: hardware and software development of RoHS VetComUnit with outsourced firm Results: product was going obsolete, kept product line aliveDeveloped: catalog of electronic parts for PCBAs for enterprise database application Results: organized part lists for commonality and obsolescence identification for database application, allowed vendor to keep products in state of manufacturabilityImplemented: streamlined process for RoHS compliant change orders Results: existing change order system was too encumbered to allow necessary fast changesPerformed: surveillance and changes of alternate electronic parts to prevent obsolescence Results: kept product lines active because obsolescence not able to creep into designs
