Principal Consultant, Gaderbas Embedded Systems, San Francisco, CA - June 2007 - Present
Embedded systems analysis, design and development on a contract basis. Work to date has included FPGA and ARM7 projects. Client references available upon request.
Senior Embedded Software Engineer, Veris Industries, Tigard, Oregon — April 2006 - May 2007
Wrote firmware for two revenue-grade power meter products including LCD driver, menuing system, interrupt handlers, device drivers (LCD, ADC, memory, SPI, I2C, UART) and serial communications.
Project Lead Engineer, Engelhard, Inc (Acquired by BASF 2/05)
Portland, Oregon — February 2005 - March 2006
Lead engineer for design of a multi-channel pyrometer system for high-performance semiconductor processing. Designed the firmware and worked with an outside consultant to complete FPGA and circuit design including a bulk transfer mode USB interface. Worked with end-customer to tune and finalize real-time closed-loop control. Oversaw product through FCC, UL, SEMI and CE certifications.
Sr. Electronics Engineer, Engelhard, Inc., Portland, Oregon — February 2002 - January 2005
Designed firmware for the companyÕs EXACTUS series of temperature measurement products running on TI TMS320 series DSPs. Project included signal processing, custom floating-point algorithms, peripheral drivers (SPI, I2C, ADC, UART) and serial communication protocols (RS-485, Modbus, proprietary). Played key engineering advisory role to management in getting products to market.
ASIC Design Engineer, PMC-Sierra Inc. — October 1997 - April 2001
Design of logic blocks for Gigabit Ethernet and SONET full-custom ASIC products. Developed testbenches, test logic insertion (BIT, JTAG), synthesis and timing scripts (TCL, Perl). Worked as part of team to complete four successful device tape-outs. Cell sizes down to 0.18um, core frequencies up to 400Mhz and SERDES rates of up to 10Gb/s.
Product Design Engineer, Planar Systems, Inc. — May 1996 - September 1997
Designed firmware and circuit boards for a flat panel display targeted at installation in FAA towers. Firmware included serial communications, touch screen driver, temperature monitoring, power and brightness control. Designed battery operated power supply for a portable medical computer.
Firmware Engineer, Fial Telecom Monitoring Solutions, Portland, OR — June 1994 - April 1996
Wrote the embedded software for the companyÕs 3031 Uplink Power Controller. The product uses open-loop control to optimize the amplitude of satellite uplink signals. Design included custom optimized floating point routines, serial communications and drivers for ADC/DAC and control panel. In this role, also developed in-house test and calibration fixtures for cable TV and telecom products.
Technician, Fial Telecom Monitoring Solutions, Portland, OR — February 1989 - May 1994
