FIRMWARE ENGINEER

Gary Urista *******@*****.*** 541-***-****

Technician/Electronic Design Engineer/Software Engineer

SUMMARY:

• 20+ years experience with electronics and microcomputers. During that time, worked as a technician, Electronic Design Engineer, and as a Software Engineer.

• The majority of the last six years I have been telecommuting for companies in San Diego and Chicago.

• Most of the embedded programming was originally done using assembly language and when the compilers got better, started using “C”. Almost all embedded work is now done in “C” with just a little sprinkling of assembly code.

• Much experience writing “C” and C++ programs for PC’s. The PC based programs are usually done to provide a user interface for testing, device control, or data gathering/logging.

• Controlled the design and implementation from the ground up.

• Usually designed the hardware and software from the conception stage, developed hardware enclosures, and even did the product documentation.

• Programmed embedded firmware in “C” (Atmel, 8051, PIC, Ubicom IP2022 and Hitachi H83067 microcontrollers).

• Did Visual C++ programming on a PC to test and control the hardware.

• Utilized various In Circuit Emulators to aid in the design and trouble shooting of the designs.

• Gained a great deal of experience designing electronic hardware.

• Designed and built products which were manufactured for sale and hardware used to test manufactured products.

PROFESSIONAL EXPERIENCE:

REMDACS 2007 - Present

Owner

• REMDACS offers R&D, software/firmware design, and electronic hardware design for several companies throughout the US.

• Products included commercial lighting control and home automation products.

Long Term Clients Included:

• Simply Automated Carlsbad, CA Home Automation products

Helped do maintenance revisions to the existing products correcting any software bugs and implementing improvements. Helped design hardware and firmware for several new products using new Homeplug command and control (HPCC) processors from Yitran.

• Axis Technologies Inc. Lincoln, NE Fluorescent Lighting Ballast Manufacturer

Designed a microprocessor based fluorescent lighting ballast. The ballast was designed to help save energy by dimming automatically when abundant sunlight was available. The ballast was able to be setup using an infrared remote control

Simply Automated Inc. August 2003 - 2006

Senior Software Engineer

• Responsible for developing embedded firmware for products and for developing test hardware for testing manufactured products. The processors ranged from small PIC processors used for UPB powerline communication to Ubicom processors used for an embedded Ethernet device. The Ubicom based device connected to a network and controlled lighting etc. via telnet sessions or using a built in web server.

• Developed the embedded firmware using C and did all software used on the PC using Visual C++.

Millennium Flight Systems January 2005 – July 2005

Hardware/Software Engineer

• Helping to develop electronic based controls for small aircraft. By replacing mechanical linkage with electronic controlled devices such as servo motors, the aircraft will be more manageable under normal operation and in emergency situations.

• Developing most of the hardware and writing all of the firmware and software for the system.

Excelsus Technologies Inc. October 1999 – August 2003

Senior Software Engineer

• Excelsus manufactures filter products for high speed Internet connections such as DSL. They also manufacture telephone line test equipment.

• Responsible for writing firmware (in “C”) for telephone line test equipment (manufactured products) and in house test equipment. One product, the Microtester, measures only 2”x2” but is able to measure the resistance and capacitance of a telephone line. Using custom algorithms, were able to measure the length of the line, know whether a phone is off the hook, sense a ringer (phone is on hook and line is OK), or whether the line is damaged (cut, shorted, water in the line, etc.).

• Also write control programs written in Visual C++ to control the test equipment and to display (both graphically and numerically) the test results.

Tempo Research Inc. January 1999 – October 1999

Senior Software Engineer

• Tempo manufactures a broad line of telephone line test equipment.

• Was responsible for writing firmware (in “C”) for telephone line test equipment.

• The devices were operated using a graphical user interface written in “C”.

City of Eugene June 1997 – June 1998

Network Technician

• Part of a team that is responsible for the maintenance of City computers and equipment. There are over 1000 PCS plus many other peripherals at several sites through out the greater Eugene area.

• Help with a city wide computer hardware/software upgrade. During the last year all the computers were upgraded to Windows 95 (along with updated software). Also hundreds of computers were replaced with more up to date systems.

• Assembled computers, loaded software, and installed the computers.

• Also responsible for replacing components in computers (floppy drives, hard drives, etc.), reformatting hard drives, installing/updating software, replacing ribbons and toner cartridges in printers, installing new printers, etc.

• Helped users who were having difficulty using their computers.

Owner

• Owned restaurant

Cadix International Inc. April 1996 - December 1996

Software Engineer

• Cadix is a developer of multi-platform CAD software used for the development of printed circuit boards.

• Responsibilities included writing software routines for the CAD programs, such as routines to add dimensioning lines and dimension text to the drawings.

• Was responsible also for software QA. This involved writing test procedures for the software modules and identifying all problems with the software.

Cottage Grove High School September 1995 - March 1996

Technology Specialist

• Responsible for the maintenance of School computers and equipment

• (75 Macintosh and PC's) plus overseeing main computer lab (30 workstations + 5 printers)
