Senior Embedded Firmware Engineer
“Bringing the Hardware to Life”
Summary
I am an accomplished senior firmware engineer with twenty-four(24) years of experience developing microcode for a wide variety of processors, enabling needed functionality and communication with peripherals and external devices. I have five(5) years of experience developing on a debian linux based arm platform, including embedded Qt. I have extended the board support packages by adding drivers, and hardware descriptions in LTIB and Yocto, and maintained the base kernel packages and drivers for kernels 2.6.38 through 3.14.28 (device tree). I have also brought up the android kernel with modified touch screen drivers for the Nitrogen 6x board and the Freescale SabreSd board.
Accomplishments
• Linux kernel driver development focusing on embedded arm systems
• Hardware debugging using Salae logic analyzers, oscilloscopes, dvms, etc.
• Microcontoller code development for a wide variety of processors from 68HC11 up to Stellaris arm processors
• Developed video graphics drivers for emerging VGA technology which formed the basis for a video chart recorder system.
• Created device drivers for pSos operating system in process controller family
• Developed bootloader firmware for PIC18F allowing it to be completely reprogrammed via I2C bus
• Developed graphics emulator for the PC enabling the development team to write and test graphics code for the product family. This eased emulator scheduling problems, reduced the need to rewrite graphics code, and reduced the number of emulators needed to complete the project
• Managed multiple overseas and domestic contract manufacturers, including full turnkey, partial kitting, and full kitting projects. Researched and approved component substitution for the contract manufacturers
• Adapted and enhanced complex manufacturer example code framework to run successfully on different hardware and peripherals
• Extended product line by developing related family modules. This increased market share and revenue for the company, while making it easier and cheaper for customers to install a reliable point-of-sale audio system
• Provided customer technical support for internal sales, distributors, and end users on our product line when technical support personnel were unavailable. This eased the burden on the regular technical support staff, reducing the required technical support staff size
• Redesigned printed circuit boards for a rifle range target retrieving system using off-the-shelf parts available from multiple manufacturers whenever possible. This protected the company from having to research replacement parts as component manufacturers phased them out
• Taught myself needed skills as the various projects required them. Learned PCB layout, processors, and tool chains saving the company from having to add employees with the needed skills.
Strengths
Positive: Looking for the positive in any situation, my enthusiasm and optimism are contagious, and lift all with whom I come into contact.
Learner: I have a proven track record of learning new skills and applying them successfully to my work, growing to fit the needs of my assignments.
Reflective: I spend quite a bit of time pondering problems and possible solutions. I bring my reflective nature to bear on them, seeking the best resolution for any situation.
Inclusive: By nature, I try to build up teams by bringing in otherwise overlooked talent. Being a people person, I try to create common ground and team-centric work environments.
Studious: I am always seeking insights and different perspectives on any topic. This constant thirst for knowledge allows me to contribute ideas and perspectives that are often outside of conventional thinking, and contribute greatly to the success of my endeavors.
