SUMMARY: Strong technical lead of multi-discipline technical development. Proven ability to bring products to market. Knowledgeable in software, hardware, analog, technologies necessary to technically lead teams.
Specialist in board bringup from initial design through production with emphasis on U-Boot, the Linux kernel and Buildroot root file system creation.
EXPERIENCE:January 2011 Present Econolite, Anaheim CA. (Project 1)
Senior Software Consultant
Currently mentoring software and hardware engineers as a 2nd project nears completion for sustaining engineering.
Have taken two projects from concept through production release. In both cases, this involved board bringup with scope & logic analyzer in concert with hardware engineers, setting parameters for flash, ram and ethernet.
Provided documentation and training for sustaining engineers for these two products.
First was U-boot & Linux-2.6.35 on an MPC8321 with NOR flash. Second was U-boot and Linux-2.6.37 on an AM3517 ARM. Both with BDI-2000 JTAG.
January 2010-January 2011 Pulse-Link, Carlsbad CA
Senior Software Engineer
