Description: Develop embedded software and device drivers for secure POS terminals.

Company: Torpedo Engineering
Span: Jul 2007 – present
Description: This is my personal business. Custom circuit, firmware, and mechanical design. Past projects have included custom motor controllers, ethernet-based mobile video broadcasting pan-tilt controllers, and custom fabrication (machining).

Company: Honeywell
Span: Jun 2007 – Jan 2010
Description: Research and develop hardware/firmware for motion detectors used in commercial and residential security systems. Production is high volume and all designs are implemented with manufacturability, cost, and sustainability in mind at all times.

Company: California State University, Sacramento (CSUS)
Span: Feb 2007 – May 2007
Description: Worked with Shriners Hospital for Children and CSU, Sacramento biomedical engineering department to develop a mobile sensor platform for use in the clinical study of children with cerebral palsy. The sensor monitored and characterized falls generating a profile of the subject which includes frequency of falling and overall activity level over several weeks of use. Responsible for power management, signal conditioning, and PCB layout.

Description: Supported several hundred employees in the state of California with computer-related networking, printing, and database interfacing problems. Developed software-based automation tools for document data entry and information indexing.

Member, Institute of Electrical and Electronics Engineers (IEEE); Student Branch Vice President Fall 2003-Spring 2004
Co-Founder, Competitive Robotics at CSUS; Secretary Fall 2003-Spring 2004
Member, Tau Beta Pi (Engineering Honor Society); Webmaster Spring 2007
Member, Association of Computing Machinery
Tae Kwon Do – Awarded Black Belt 1994

Span: Oct 2006 – Aug 2007 (rev1), Dec 2007 – Aug 2008 (rev2)
Description: Member of a three-engineer team that designed, built and entered into competition a robot with the purpose of autonomously shooting down targets as fast as possible. Responsible for robot fabrication, electrical interfacing, and low-level microcontroller programming. Note: I am the organizer and host for this event at the annual RoboGames in San Francisco.

Span: Nov 2007 – Jul 2008
Description: Created accelerometer-based autonomous controller for high-speed slot car. The car was capable of learning the acceleration profile of a track, predicting turns and adjusting control parameters based on real-time data. Responsible for circuit design/testing, PCB layout, assembly, and low-level interface firmware.

Span: Dec 2006 – July 2007
Description: Member of a two-engineer team that designed and built 30lb translational-motion combat robot. The robot would spin at approximately 600 RPM and use acceleration feedback to time wheel braking, producing motion in a specific direction. The robot was controlled with a Nintendo Wii-mote and used Bluetooth for communication between the controller and the robot. Responsible for mechanical design and fabrication of the aluminum frame and custom gearboxes. Also responsible for electronic design, assembly of microcontroller/Bluetooth interface, and power/battery management.

Span: Sep 2006 – June 2007
Description: Designed and built a robotic video camera platform for use in recording 360-degree immersive media environments. The robot was controlled with a joystick over a wireless network using a custom UDP protocol, and designed with a linear actuator for remote camera height adjustment. Responsible for mechanical design/fabrication, and joystick/motor PC interfacing.

Span: Jan 2006 – Dec 2006
Description: Leader of four-engineer team in a year long project to design, test, and fabricate an electro-ocular based eye-tracking system. Responsible for project planning, organization, sensor circuit development, PC software, PCB layout, and integrating multiple systems with a central microcontroller interface.

Span: Dec 2002 – Jun 2004
Description: Worked in multi-disciplined team of engineers to develop and battle a 340lb fighting robot. Wrote, submitted, and presented grant proposals for project funding. Selected and implemented 7200W DC motor control system. Outfitted and calibrated all necessary safety and fail-safe equipment as described in competition rules.
